METEO 101Understanding Weather Forecasting3
Fundamental principles of synoptic and physical meteorology, satellite and radar imagery, and data analysis in the setting of mid-latitude weather forecasting. METEO 101 Introduction to Weather Forecasting (3) (BA) This course meets the Bachelor of Arts degree requirements. Never before has the quantity of available weather information so far exceeded the quality of the public's understanding of atmospheric science. Meteorology 101: Understanding Weather Forecasting aims to help correct this imbalance by helping students develop the knowledge and skills they need to become critical consumers of weather information. Students who successfully complete Meteorology 101 will be able to apply knowledge of fundamental concepts of atmospheric science to discriminate between reliable and unreliable weather forecasts, and to explain what makes one forecast better than another. To ensure that students develop the knowledge and skills required to critically assess public weather forecasts, Meteorology 101 will provide an apprentice-training environment that will encourage students to learn forecast mid-latitude weather themselves. They will discover that weather forecasting involves sophisticated data analysis techniques, a thorough understanding of atmospheric science, and strong verbal and graphic communication skills. As it develops these competencies, METEO 101 will fulfill the goals established for Penn State General Education courses in the Natural Science knowledge domain. The intended audience includes undergraduate students at University Park and other Penn State campuses, as well as adult learners in the weather information industry and weather hobbyists worldwide. To reach this diverse audience, METEO 101 will be offered through the University's World Campus in a Web-based, instructor-led format. Currently in development in collaboration between the Department of Meteorology, the EMS e-Education Institute, and the World Campus, METEO 101 will combine digital video, audio, simulation models, virtual field trips to on-line weather data resources, text, and interactive quizzes that provide instantaneous feedback. The course will provide unprecedented access to one of the world's most distinguished meteorology programs. METEO 101 will be offered three times each year during the spring, summer, and fall semesters to an expected audience of about 300 annually.
METEO 122Atmospheric Environment: Growing in the Wind3
Atmospheric Environment: Growing in the Wind is for students who are interested in learning about the dynamic effects of weather on plants and animals. It is about how processes at the ground surface and in the air govern weather conditions on Earth. Growing in the Wind focuses on five major weather elements: energy, temperature, moisture, pressure and wind and how these factors influence ecosystems and habitation of our planet. Emphasis is also given to human impacts on weather and climate, and current environmental issues involving the atmosphere. The lectures are organized around the central theme that the unequal distribution of incoming solar energy (both spatially and temporally) produce temperature and pressure contrasts at the Earth's surface and in the atmosphere that in turn cause storms and control the weather and climate.
Climate change is not only a political, economic, and social crisis, it presents one of the great moral problems of our time. This course will cover the science, policy, and ethics of climate change. It fulfills general science requirements by giving an overview of the role played by such diverse scientific disciplines as chemistry, earth systems, ecology, and geology in understanding our changing climate while also exploring mitigation and adaptation strategies being developed in the fields of engineering, forestry, agriculture, and others. It fulfills humanities requirements by delving into the ethical dimensions of climate change, including religious and humanistic theories of human flourishing, deontological and teleological theories of ethics, and analysis of specific choices addressed by international negotiators. A hallmark of this course is using Penn State as a 'living laboratory' by taking advantage of both faculty expertise and the realworld activities of the Office of Physical Plant. Every week, students will interact with experts from various quarters of the University in order to see how climate change is being approached in a multi-disciplinary fashion. The first third of the course will feature guest lectures by EMS faculty working on paleoclimate, modeling, carbon sinks, ocean acidification and other aspects of climate science. The second portion will engage humanists, economists, historians, and artists at Penn State. The third will include tours of Penn State facilities, such as the East Campus Power Plant, and interviews with researchers developing new energy and sequestration technologies. In addition to exams and papers, students will prepare for a mock negotiation by learning about the energy profile and history of assigned countries. They will then have to set specific CO2 and temperature goals and come up with solutions to achieve these. The goal is to understand the role placed by ethical ideals in the pragmatic process of producing an equitable solution. In short, this course will give students the tools to understand the basic science of climate change and its ethical implications. Students will come away with a better sense of the moral dimensions of this phenomenon and the implications for human civilization and for the biosphere.
Introduction to the collection, display, and application of weather observations and numerical forecasts used by the operational meteorologists. Students who have passed both METEO 200A and 200B may not schedule this course for credit.
Forecast methods/data discussed prior to nightly weather forecast entry. Satisfactory performance will be determined by attendance and forecast accuracy. METEO 215 Weather Forecast Preparation Laboratory (0.5 per semester/maximum of 4) Students will learn basic weather forecasting techniques and identify appropriate sources of weather information that will assist them in weather forecast preparation. Forecast accuracy will be judged against peer groups at Penn State and several other institutions of higher learning across the U.S. and Canada through WxChallenge (or a similarly run program), a national weather forecasting contest. The bulk of the class time will be spent preparing weather forecasts for five different U.S. cities, each for two consecutive weeks. Cities from different climate regimes will help familiarize students with forecasting challenges from across the country. In addition, the previous day's weather forecast difficulties and ways to improve forecast accuracy will be discussed. The remaining weeks of the semester will be devoted to in-depth analysis of forecast errors and ways to keep improving forecast quality. Satisfactory performance is determined through attendance records and weather forecast contest results. The course should be taken in BOTH the fall and spring semesters each year for maximum learning potential. METEO 215 may be repeated up to 8 times.
Applying atmospheric principles to the tropics, with an emphasis on the development, structure, prediction and destructive impact of hurricanes. METEO 241 Fundamentals of Tropical Forecasting (3) Worldwide, approximately 80 tropical cyclones develop each year. This global annual average of tropical cyclones is small in comparison to the thousands of low-pressure systems that routinely parade across the middle latitudes each year. Yet tropical storms and hurricanes garner far greater attention from meteorologists and the media. The obvious reason for this lopsided focus is that tropical cyclones can inflict great devastation to life and property.One of the primary goals of Meteorology 241: Fundamentals of Tropical Forecasting is to give students a working knowledge of hurricanes and tropical storms so that they can become critical weather consumers. For example, when a hurricane bears down on the coast of the United States, the media often portray the storm as a monster capable of laying waste to anything in its path. In METEO 241, students will understand that the initial fury of a land-falling hurricane is focused within a swath of coastal area approximately 30 miles long or less.To ensure that students develop the knowledge and skills required to critically assess weather forecasts issued by the National Hurricane Center, METEO 241 will provide, like METEO 101, an apprentice-training environment. Under the tutelage of professional weather forecasters, students, in their role as apprentices, will also work toward the goal of creating their own tropical-weather forecasts.In the process, students in METEO 241 will learn about the pitfalls of forecasting the tracks and intensities of tropical storms and hurricanes as they actively work with output from sophisticated numerical models available on the Internet. Moreover, successful students will apply their knowledge of the fundamental concepts of atmospheric science in order to competently evaluate forecasts issued by the National Hurricane Center in Miami and the Joint Typhoon Warning Center in Honolulu.Students will also gain a broad perspective of the general weather and oceanic patterns in the tropics. For example, students will learn about El Nino and La Nina. In the process, they will discover that El Nino and La Nina are not to blame for every unusual weather event that occurs anywhere in the world. It should be noted here that METEO 241 will be one of four courses required for students to earn a Certificate of achievement in Weather Forecasting, a unique online program offered through Penn State's World Campus. The three other courses that will comprise this online program are METEO 101: Understanding Weather Forecasting, METEO 361: Fundamentals of Mesoscale Weather Forecasting and METEO 410: Advanced Topics in Weather Forecasting.To facilitate the learning objectives, METEO 241 will include the use of digital video, audio, simulation models, virtual field trips to on-line resources for weather data, text, and interactive quizzes that provide timely feedback.To demonstrate their mastery of the learning objectives, students will complete automated online quizzes, actively engage in online discussion groups focusing on real-time weather, and publish, to a personal 'e-portfolio', four comprehensive projects that will explore timely case studies related to weather forecasting. The e-portfolio will take the form of a Web site that students initially create during the second course of the program (METEO 241 or METEO 361). Students will augment their e-portfolio as part of the requirements for METEO 241, METEO 361 and METEO 410. They will also use the space to reflect on their learning.At the end of the program, students will make a final e-portfolio entry that highlights their program accomplishments. In this way, the e-portfolio will serve both as a showcase of a student's work for the purpose of course assessment and as a chronicle of a student's achievements during the program. By using their Penn State personal Web space to host their e-portfolios, students will be able to share their work not only with program faculty and students, but also with external audiences, including potential employers. Upon successful completion of the program, graduates will receive a copy of their final e-portfolio on CD-ROM.
METEO 273Introduction to Programming Techniques for Meteorology3
Algorithm design and implementation for meteorological analysis and forecasting. Algorithm design and implementation for meteorological analysis and forecasting, including access to datasets in meteorological common data formats. The objectives of this course are to introduce the student to fundamental programming concepts, such as variables, flow control, and syntax, to apply those concepts to solve meteorological problems couched in the analysis of datasets in meteorologically-relevant common data formats, and to familiarize students with appropriate programming languages and their application to meteorological analysis or forecasting problems on regional and/or global scales.
An introduction to the fundamentals of atmospheric dynamics, physics, and chemistry. METEO 300 Fundamentals of Atmospheric Science (4)This course prepares students for their 400-level meteorology courses by laying a solid foundation in the application of physical, chemical, and mathematical principles to a broad range of atmospheric phenomena. Students are introduced to fundamental concepts and applications of atmospheric thermodynamics, radiative transfer, atmospheric chemistry, cloud microphysics, atmospheric dynamics, and the atmospheric boundary layer. These topics are covered broadly but in enough depth to introduce students to the methods atmospheric scientists use to describe and predict atmospheric phenomena. The course is designed to be taken by sophomore meteorology students as well as by students in related disciplines who have an adequate mathematical and physical background.
METEO 332NScience and policy of global greenhouse gas emissions and management3
This interdomain course introduces students to the science and policy of greenhouse gas emissions. The course focuses on emissions from natural sources, energy production and food production. Policy components will introduce students to the fundamentals of environmental policy and examine key policy options for mitigating and managing emissions. Global in scope, the course will also address how emissions and policy options differ in developed and developing countries. Topics will include overviews of the global carbon cycle, agriculture and land use change emissions, history of global energy use and production, overview of global climate change policy, frontiers in climate, energy and agriculture policy, amongst others.
METEO 361Fundamentals of Mesoscale Weather Forecasting3
Applying atmospheric principles to small-scale weather systems, with an emphasis on the conceptual modeling and short-range prediction of severe thunderstorms. METEO 361 Fundamentals of Mesoscale Weather Forecasting (3) When outbreaks of severe weather occur, dire warnings for tornadoes, large hail or damaging straight-line winds urgently scroll across the bottoms of television screens. Simultaneously, television weathercasters warn viewers to "take cover immediately". Yet, because of the limited spatial and time scales of severe thunderstorms, the areas affected by tornadoes, large hail and damaging straight-line winds often turns out to be relatively small (sometimes as small a tenth of one percent of the original "watch area"). There is no doubt that people should be prepared to take definitive action to protect their lives and the lives of their families when outbreaks of severe weather occur. But the overall impression that entire counties or cities will be destroyed by severe weather can be, and frequently is, misleading. One of the primary goals of METEO 361: Fundamentals of Mesoscale Weather Forecasting is to give students a scientifically grounded perspective of the spatial and time scales of typical outbreaks of severe weather. In the process, students will become better weather consumers. To gain such insights, students will learn conceptual models of the life cycles of severe thunderstorms and will then apply them in real-time outbreaks of severe weather. In the final analysis, students will be able to more accurately weigh the information being disseminated by the media and the Storm Prediction Center in Norman, Oklahoma.To ensure that students develop the knowledge and skills required to critically assess public weather forecasts, METEO 361 will provide, like METEO 101, an apprentice-training environment that will guide students, under the tutelage of professional weather forecasters, to actively learn how to create their own mesoscale-weather forecasts. In the process, METEO 361 will reinforce the notion that weather forecasting involves sophisticated techniques of data analysis and a thorough understanding of atmospheric science. METEO 361 will also stress that the clear communication of the forecast requires strong verbal and graphic communication skills.Using conceptual models and real-time radar and satellite imagery in concert with output from numerical models designed specifically for mesoscale forecasting, students will predict severe weather on time scales of a few hours to one day. For example, students will be given a litany of web-based tools and asked to place their own "watch box" for severe weather. Students will then be asked to verify and discuss the outcomes of their forecasts. For more general outlooks of severe weather (time scales of one to two days), students will use output from the numerical models that were introduced in METEO 101 to identify the areas likely to be at risk for severe weather. It should be noted here that METEO 361 will be one of four courses required for students to earn a Certificate of Achievement in Weather Forecasting, a unique online program offered through Penn State's World Campus. The three other courses that will comprise this online program are METEO 101: Understanding Weather Forecasting, METEO 241: Fundamentals of Tropical Forecasting and METEO 410: Advanced Topics in Weather Forecasting.To facilitate the learning objectives, METEO 361 will include the use of digital video, audio, simulation models, virtual field trips to on-line resources for weather data, text, and interactive quizzes that provide timely feedback.To demonstrate their mastery of the learning objectives, students will complete automated online quizzes, actively engage in online discussion groups focusing on real-time weather, and publish, to a personal 'e-portfolio', four comprehensive projects that will explore timely case studies related to weather forecasting. The e-portfolio will take the form of a Web site that students initially create during the second course of the program (METEO 241 or METEO 361). Students will augment their e-portfolio as part of the requirements for METEO 241, METEO 361 and METEO 410. They will also use the space to reflect on their learning.At the end of the program, students will make a final e-portfolio entry that highlights their program accomplishments. In this way, the c-portfolio will serve both as a showcase of a student's work for the purpose of course assessment and as a chronicle of a student's achievements during the program. By using their Penn State personal Web space to host their e-portfolios, students will be able to share their work not only with program faculty and students, but also with external audiences, including potential employers. Upon successful completion of the program, graduates will receive a copy of their final e-portfolio on CD-ROM.

Exploring highly specialized topics and techniques in weather forecasting that span from mesoscale to planetary spatial scales and short-term to long- range time scales. METEO 410 Advanced Topics in Weather Forecasting (3) T.H. Huxley's passage from Biogenesis and Abiogenesis -- 'The great tragedy of Science - the slaying of a beautiful hypothesis by an ugly fact' (1870) -- will serve as the springboard for learning in METEO 410. In the spirit of a 'beautiful hypothesis,' forecasters' diagnoses of the present state of the atmosphere and their prognoses for how the atmosphere will evolve with time may be scientifically sound. Yet, local weather can turn out dramatically different than the intent of the forecast (the ugly fact). To compound this 'great tragedy of Science,' weather forecasters routinely spend most of their preparation time on local details, particularly when the weather tends to get more interesting.Nonetheless, there are 'master forecasters' who regularly avoid great tragedies in weather forecasting. Master forecasters will prudently weigh the length of the forecast time as well as interactions between weather features on the hemispheric, synoptic, meso and local scales while, at the same time, they will adroitly use an array of forecasting tools to arrive at a high-quality local forecast. With the prudent and seasoned approach of the master forecaster in mind, METEO 410 will provide students with a master apprenticeship in weather forecasting. As master apprentices, students will learn highly specialized tools and techniques that will help them to hone and expand their overall forecasting skills. For example, students will learn a new technique for forecasting rare and extreme weather that is based on assessing departures of specific meteorological fields from climatological norms. In the process, students will study rare historic events, such as the great ice storm across northern New England and eastern Canada in 1998. Along the way, students will learn some basic statistics, including climatological means and standard deviations. As master apprentices, students will also learn about medium-range forecasting (three to seven days into the future) and medium-range computer models. Students will learn how to implement modern prediction techniques, such as ensemble forecasts from computer models. Master forecasters increasingly take advantage of this avant-garde technique in short to medium-range forecasting. Unique learning modules, which run the gamut from forecasting wildfires to learning about the influence of the North Atlantic Oscillation on long-range forecasts (seven days or more), will provide students with the tools to understand the bases for all the forecasts they see on television, hear on the radio, read in publications such as Weatherwise, or access on the World Wide Web. For example, students will learn about the forecasting products issued by the Climate Prediction Center, which include seasonal outlooks that focus on the seasonal impacts of La Nina and El Nino. To facilitate the learning objectives, METEO 410 will include the use of digital video, audio, simulation models, virtual field trips to on-line resources for weather data, text, and interactive quizzes that provide timely feedback.It should be noted here that METEO 410 will be one of four courses required for students to earn a Certificate of Achievement in Weather Forecasting, a unique online program offered through Penn State's World Campus. The three other courses that will comprise this online program are METEO 101: Understanding Weather Forecasting, METEO 241: Fundamentals of Tropical Forecasting and METEO 361: Fundamentals of Mesoscale Weather Forecasting.To demonstrate their mastery of the learning objectives, students will complete automated online quizzes, actively engage in online discussion groups focusing on real-time weather, and publish, to a personal 'e-portfolio', four comprehensive projects that will explore timely case studies related to weather forecasting. The e-portfolio will take the form of a Web site that students initially create during the second course of the program (METEO 241 or METEO 361). Students will augment their e-portfolio as part of the requirements for METEO 241, METEO 361 and METEO 410. They will also use the space to reflect on their learning. At the end of the program, students will make a final e-portfolio entry that highlights their program accomplishments. In this way, the e-portfolio will serve both as a showcase of a student's work for the purpose of course assessment and as a chronicle of a student's achievements during the program. By using their Penn State personal Web space to host their e-portfolios, students will be able to share their work not only with program faculty and students, but also with external audiences, including potential employers. Upon successful completion of the program, graduates will receive a copy of their final e-portfolio on CD-ROM.
Meteo 411 focuses on the description, analysis, evolution, and prediction of large-scale weather systems such as extratropical cyclones, jet streams, and fronts, with an emphasis on techniques for analyzing synoptic-scale weather situations in three dimensions. Students will develop an understanding of the fundamental underlying processes that lead to the large-scale motions that modulate weather on synoptic scales. Though not intended as a course in weather forecasting, Meteo 411 provides a solid foundation for future forecasting courses. A fundamental goal of Meteo 411 is to provide students with a framework for visualizing the vertical motion field in the atmosphere, both qualitatively and quantitatively. The vertical motion field ultimately determines, depending on the availability of water vapor, where clouds and precipitation form. To that end, students become familiar with the Norwegian cyclone model as a conceptual framework for understanding synoptic-scale weather systems, as well as the role of the upper-level flow in the development and evolution of extratropical cyclones. The principles of conservation of mass, energy, and momentum are also applied as instruments for assessing synoptic-scale motions. Finally, students will develop an understanding of quasi-geostrophy and how this framework can be used to explain the evolution of synoptic-scale weather systems. The course begins with a review of the fundamental assumptions that are commonly invoked on the synoptic scale, including the hydrostatic and geostrophic approximations. The topic of numerical weather prediction is revisited from both the theoretical and the operational standpoints, comparing and contrasting the deterministic and ensemble frameworks. To visualize the structure of synoptic-scale weather systems, a variety of analysis techniques are employed, including cross sections, plan views, three-dimensional models, and satellite and radar imagery. Pattern recognition techniques for identifying synoptic-scale regimes are explored and quantified using various zonal indices and global teleconnection patterns. These techniques are employed in each lab period where students lead a daily weather briefing that includes both an analysis of the current weather situation and a forecast of its future. Students will be able to link the mathematical descriptions of atmospheric motion with a qualitative understanding of physical processes, and apply them to the analysis and prediction of the atmosphere. Within the course framework, the following topics are also covered: thickness and its applications, thermal wind balance, potential temperature, pressure tendency equation, frontogenesis equation, ageostrophic processes, gradient wind, jet streaks, vorticity and vorticity advection, conveyor belts, self-development, quasi-geostrophic theory, potential vorticity and its applications, and the synoptic setup for severe weather.
Analysis of actual surface weather observations, with emphasis on the Norwegian cyclone model, missing or bad data, and mesoscale phenomena. METEO 413 Map Analysis (3) METEO 413, Map Analysis, is designed as a professional elective for Meteorology majors and as such it is primarily taken by fourth-year students. Third-year students who have completed METEO 411 may also register for Map Analysis. The course encourages students to tie together concepts learned in prior meteorology courses through analysis of numerous weather maps from across the northern hemisphere both at the surface and above. This is accomplished by improving the student's understanding of the cyclone model and applying that knowledge to 'real-life' analyses where data quality may be compromised and topographic and other mesoscale factors may be important. Grades are based upon the best 13 of 14 lab assignments, 2 or more quizzes, and in-class assignments. Class participation is rewarded on an extra-credit basis. METEO 413 is offered each spring; enrollment is limited to 15 students.
Issues relating to the prediction and dispersion of air pollutants are discussed. METEO 419 Air Quality Forecasting (3) Prediction of air quality is discussed from the perspective of operational weather forecasting. The chemical properties of pollutants for which public forecasts are currently made, fine-scale particulate matter and ozone, are summarized to provide the physical background for making forecasts. The impacts of weather on pollutant concentrations are discussed. Current techniques for forecasting air quality are presented and used by the students to create their own air quality forecasts. Students present air quality weather briefings and post-analysis of significant historical air quality events. To take this course, students must have the background provided in a basic course in chemistry and a basic course in meteorology that covers weather systems governing the transport of air pollution.
Balanced and unbalanced flows, vorticity, circulation and potential vorticity, an introduction to wave dynamics and stability analysis, and a quantitative discussion of the general circulation. Meteo 421 Atmospheric Dynamics (4) This course builds on the foundation laid in METEO 300, Fundamentals of Atmospheric Science, by presenting applications of the equations of motion to the description of a variety of atmospheric motions. The intrinsically rotational aspects of large-scale atmospheric motions are presented through a discussion of vorticity dynamics (including both relative and planetary vorticity) and the related circulation theorems of Kelvin and Bjerknes that culminate in potential vorticity thinking. The contrast between oscillating and unstable atmospheric systems is highlighted using the examples of gravitational, inertial, and shear instability, and the parcel and perturbation methods are introduced for studying these systems. An introduction to wave dynamics presents the concepts of phase and group velocity with applications to gravity, inertial, and Rossby waves, and to geostrophic adjustment. Finally, the general circulation, including the major zonal wind systems (e.g., the mid-latitude westerlies) and the major overturning cells (Hadley and Ferrel cells) is discussed quantitatively to provide a description of planetary-scale motions.
Survey of advanced dynamical topics including instabilities, numerical modeling, and others of current interest. METEO 422 Advanced Atmospheric Dynamics (3)This course in atmospheric dynamics covers advanced topics, including instabilities that lead to the development of various atmospheric phenomena at the synoptic and smaller scales, numerical modeling principles and applications, topographic gravity and Rossby waves, understanding of the general circulation that can be used for extended-range forecasting, and frontal structure and frontogensis. Some additional topics will vary at the discretion of the instructor.
METEO 426 will provide students with a practical understanding of the structure of numerical weather prediction (NWP) models in the context of their application to real world precipitation forecasting. The course combines lecture material on the inner workings of NWP models with a forecasting module that applies the lecture material to daily precipitation forecasts. The course begins with a full description of the mathematical backbone of NWP models - the primitive, or governing, equations. The primitive equations that describe the future state of the atmosphere, given some initial state, are a set of non-linear, partial differential equations that are only solvable by numerical methods. The sophistication of numerical methods, in turn, depends on available computing capacity. A discussion of the historical development of simplified NWP models in the context of limited computing resources follows. While the advent of modern computers allowed for the explicit computation of the primitive equations, their use in operational forecast settings uncovered additional important theoretical limitations on forecast skill. In particular, the future state of the atmosphere is extremely sensitive to initial conditions yet there are insufficient observations to fully initialize an NWP model. Techniques for initializing NWP models - called data assimilation - were and continue to be a key source of model error. As a result, we cover these methods in detail. Beyond initial condition uncertainty, there are fundamental limits on the predictive skill of NWP models. These limits, a consequence of the fundamentally non-linear dynamics of the atmosphere, were first described by Edward Lorenz and usually referred to as "chaos theory." For operational weather forecasting, the implication is that single, deterministic models are necessarily limited in skill, even with near-perfect initial conditions. As a result, operational forecast centers have moved towards ensemble-based forecasting. The development and use of ensemble models are discussed in detail in this class. Next, the model must be moved forward in time. Basic numerical methods used to advance the model in time, typically using finite difference techniques, are described and the recent shift to finite volume methods are introduced and discussed in the context of the latest NWP models. We then describe parameterization schemes that NWP models use to account for phenomena not directly resolved by the model. We discuss several important schemes relevant to precipitation, including convective parameterizations and microphysics, and the planetary boundary layer. The course concludes with a review of one of the latest operational NWP models.
In METEO 434, students will learn the basic operating principles and applications of weather radar, a primary observing platform for both operational and research meteorologists. In particular, students will learn the fundamentals of radar data acquisition, signal processing, and interpretation for measurements of weather phenomena. In order to successfully achieve these skills, students will master the following concepts: the basics of radar engineering, design, and operation; the physics of electromagnetic radiation, its propagation through the stratified atmosphere, polarization and phase shifts, and scattering from various hydrometeors; the physical properties of atmospheric scatterers, and how the physical properties of hydrometeors (e.g., size, shape, dielectric constant, orientation) affect the scattering signal. Lectures will frequently involve real-world data examples, theoretical considerations, and practice problems. In addition, several lectures will be devoted to recent technological or scientific advances published within the last 1-2 years, in order to provide students with an updated and working knowledge of the field. When practical, the course will include a field trip to a National Weather Service Doppler radar facility, most likely the system in Moshannon State Forest in central Pennsylvania. With this knowledge and these tools in hand, the remainder of the class will heavily focus on the interpretation of radar signals in weather phenomena, with particular emphasis on the interpretation and applications of dual-polarization weather radar data. To this end, one class per week will involve the discussion and interpretation of student-provided radar images. As the semester progresses, the students are expected to incorporate additional depth of understanding and newly discussed radar variables into these discussions. Students will actively participate in the course through bringing real-world examples of radar observations to class for presentation and discussion. They will be required to access data from the internet or smart phone app, organize it for a computer-based presentation, write a brief description, give the in-class presentation, and lead the subsequent discussion. In addition, the students will work towards a term project that is a case study of a high-impact weather event of their choosing. This project provides students the opportunity to master ordering data from the internet, downloading it, processing it, reading it into common coding languages, and creating graphics for display. In addition, part of the project will involve quantitative data analysis or manipulation, emphasizing computer coding and data handling skills. The semester-long project will culminate in a final presentation and report synthesizing their newly acquired knowledge and skillsets.
Elements of earth-sun geometry, radiative transfer, photochemistry, remote sensing of the atmosphere, physical climatology, climate forcing. METEO 436 Radiation and Climate (3)This course covers radiation and how it interacts with the atmosphere and earth's surface to drive motions in the atmosphere. The fundamentals of radiative transfer at the molecular level, including absorption, scattering, transmission, and emission of radiation by matter, are discussed and applied to help describe the earth's energy budget. Crucial to understanding these processes in the atmosphere are the interactions of radiation with water in the vapor, liquid, and solid states. Applications of radiative transfer to the understanding of seasons and of climate and climate change are presented as well.
Properties of aerosols and clouds, cloud nucleation and precipitation processes, atmospheric electricity, cloud and precipitation chemistry, biogeochemical cycles. METEO 437 Atmospheric Chemistry and Cloud Physics (3)This course develops an understanding of how the physical and chemical properties of the atmosphere influence cloud and precipitation formation, as well as how clouds in turn affect the properties of the atmosphere. The roles that chemistry and clouds play in modulating weather, climate, and atmospheric electricity are also treated.
Theory and practices used in measurement and analysis of meteorological variables. METEO 440W Principles of Atmospheric Measurements (3) The standard theories and practices used in measurement and analysis of atmospheric variables are surveyed in the lecture portion of the course. The laboratory portion of the course provides students hands-on experience with using standard and self-produced instruments to make reliable measurements and with analyzing meteorological observations to determine their significance. In the laboratory reports, students learn the fundamentals of appropriate scientific writing to summarize the objectives of the lab exercise, to provide an analysis of the observations, and to critique the results. The initial drafts of these reports are evaluated critically by the instructors and teaching assistants and then are revised by the students based on these evaluations. Discussion of scientific writing and of proper report protocols are presented in the course as well.
Air-sea interaction, wind-driven and thermohaline circulations, upwelling, El Nino, waves, and tides. METEO 451 Elements of Physical Oceanography (3) The primary objective of this course is to describe the circulation of the ocean and present a theoretical basis for understanding it. The focus is on the large-scale, basin-wide features of the ocean circulation, such as: 1) the subtropical ocean gyres that contain the wind-driven western boundary currents like the Gulf Stream, 2) the equatorial oceans that respond rapidly to external forcing to produce phenomena like El Nino, and 3) the thermohaline circulation that acts as a slow regulator of the earth's climate. A main goal is to demonstrate to meteorology students that the ocean is not a static, passive lower boundary to the atmosphere but a dynamic, evolving entity that is intimately coupled to the atmosphere through the exchange of heat, momentum, and water. Thus the oceans affect weather and climate. Students are evaluated on their comprehension of the relevant physical processes (as determined by written examinations) and by term papers and laboratory reports or a combination of the two. This course will be offered annually with an enrollment of about 12 students.Class size, frequency of offering, and evaluation methods will vary by location and instructor. For these details check the specific course syllabus.

METEO 469From Meteorology to Mitigation: Understanding Global Warming3
Examination of global warming and climate change: the basic science, projects, impacts, and approaches to mitigation. METEO 469 From Meteorology to Mitigation: Understanding Global Warming (3) Human-caused climate change represents one of the great environmental challenges of our time. As it is inextricably linked with issues of energy policy, a familiarity with the fundamentals of climate change is therefore critical for those looking to careers in the energy field. To appreciate the societal, environmental, and economic implications of policies governing greenhouse gas emissions, one must further understand the basic underlying science. METEO 469 serves to lay down the fundamental scientific principles behind climate change and global warming. A firm grounding in the science is then used as a launching point for exploring issues involving climate change impacts and mitigation. METEO 469 will introduce students to the basic information necessary for understanding Earth's climate, including the relevant atmospheric processes, and aspects of other key components of the climate system such as the cryosphere, hydrosphere, and biosphere. Students will learn how to do basic computations and to use theoretical models of the climate system of varying complexity to address questions regarding future climate change. Students, further, will explore the impacts of various alternative greenhouse gas emissions scenarios and investigate policies that would allow for appropriate stabilization of future greenhouse gas concentrations. The structure of the course roughly parallels the treatment of the subject matter by the reports of the Intergovernmental Panel on Climate Change (IPCC), focusing first on the basic science, then the future projections and their potential impacts, and finally issues involving adaptation, vulnerability, and mitigation. METEO 469 will combine digital video, audio, simulation models, virtual field trips to on-line data resources, text, and interactive quizzes that provide instantaneous feedback.

This upper-level undergraduate course will cover the fundamental physics of light and scattering of light by atmospheric particles. Knowledge of these processes will be applied to understand how they result in optical displays in the sky, including colors in the sky, phenomena associated with refraction of light, scattering by liquid drops and ice crystals, and electrification. The course will guide students to observe, document, and understand these beautiful and sometimes bizarre atmospheric optical phenomena. Students will make their own observations using their eyes, optical cameras, and polarization filters. The students will document their observations through regular written sky journal entries to hone their writing skills. By working together through hands-on activities and discussions, students will unlock the mysteries of these phenomena through applying the fundamental physical principles that underly all topics covered in the course. Throughout the semester, students will research a phenomenon of interest to them, culminating in a final paper on this topic. Students who have completed this course will understand the physical concepts associated with atmospheric optical phenomena and where/how to look for them, observe them, and document them.

METEO 494M Thesis Research (3). In this course, students will write a professionally structured thesis that is grounded in a solid research foundation. In the process, students will learn the elements of excellent technical science writing and effective oral presentation. This course continues the thesis research topic developed in Meteo 494H. This capstone course integrates the key elements of any well-conceived research project: a) a thorough background literature search that identifies the current understanding of a question or topic; b) the articulation of a research hypothesis that is informed by the literature search; c) the design and implementation of a plan to test the hypothesis using theoretical, experimental, and/or computational approaches; and d) conclusions regarding the validity of the hypothesis based on the data obtained in the course of the research. The main characteristic of this course is the execution of the research plan articulated in METEO 494H, interpretation of the data generated by the research in the context of the original hypothesis, and the preparation of the thesis. Research is generally performed in collaboration with faculty and graduate research assistants, using equipment and facilities in the Meteorology and Atmospheric Science department or other departments involved in the research endeavor. Occasionally, the nature of the research may require the student to collaborate with researchers outside of Penn State, perhaps even spending some time in residence at other facilities. The course culminates in the preparation of a thesis detailing the relevance and findings of the research and, at the discretion of the thesis advisor, an oral presentation about the research findings. Close coordination with the thesis advisor is a key to success in METEO 494M. Ideally, a student should meet with the advisor regularly and drafts of parts of the thesis should be shared with the advisor for feedback. Assessment of the student's progress is via grading of all components of the thesis which include the literature review and background, the statement of the problem, the design of the experimental plan, the results and discussion, the conclusions, any recommendations for future work, the reference list, and any appendices and figures. The diligence of the student in performing the research in a professional and timely fashion will also be considered.

Conceptual models and underlying physics for weather phenomena on scales from the global general circulation to turbulence. METEO 511 The Weather From Global to Micro Scales (3) Earth's weather occurs on a variety of scales from the global general circulation down to microscale turbulence. This spectrum includes synoptic scale storms whose structure and dynamics vary with latitude and topography as well as a broad range of mesoscale phenomena whose structure depends strongly on the vertical structure of the atmosphere. At these intermediate scales, each phenomenon draws energy from conditions created by phenomena of both larger and smaller scale phenomena. Thus, the full spectrum of weather phenomena is linked energetically. This course explores these linkages and the dynamics of the weather phenomena that result. Quantitative results from this theoretical analysis are then used to explain the structure and behavior of the phenomena themselves. Using both theoretical and observational methods students will gain an understanding of the full spectrum of weather phenomena including the physics and dynamics responsible for their structure, development, and evolution.
Application of atmospheric dynamics to the diagnosis and prediction of synoptic-scale weather. The primary objective of the course is to investigate midlatitude synoptic-scale weather systems from a quasigeostropic perspective. Topics include Sutcliffe's development theorem, quasigeostrophic height tendency and omega equations, midlatitude extratropical cyclones, fronts and frontogenesis, semigeostropic theory, and the potential vorticity perspective of synoptic-scale analysis. The course builds upon the dynamical understanding acquired in atmospheric dynamics and synoptic meteorology courses, and is well-suited for students seeking careers in a broad range of areas, including but not limited to air quality, weather forecasting and communications, microscale meteorology, mesoscale meteorology, and synoptic meteorology.
METEO 515PRACTICAL STATISTICS FOR ATMOSPHERIC SCIENCES3
The aim of this course is to build practical statistical tools for data analysis in the atmospheric sciences. The course will first provide the students with a solid foundation in fundamental statistical concepts, including hypothesis testing, maximum likelihood estimation, random variables, and probability density functions. Once the students are familiar with the basic terminology and concepts in statistics, the course will move on to a suite of more advanced statistical techniques that are commonly used in atmospheric science research. The advanced topics include regression analysis, nonparametric tests and resampling techniques, data reduction such as eigendecompositions and principal component analysis, time series analysis, spatial statistics, and Bayesian modeling. The emphasis will be on the sound application of these techniques and their interpretations, rather than technical foundations and derivations. The goal is to build intuition behind commonly used statistical tools and learn how to avoid potential pitfalls in their applications.
Fundamentals of fluid dynamics with an emphasis on basic concepts that are important for atmospheric and oceanic flows. METEO 520 Geophysical Fluid Dynamics (3)This is a course in the fundamentals of fluid dynamics with an emphasis on basic concepts that are important for geophysical flows, such as those in the atmosphere and ocean. Topics include kinematics, conservation laws, vorticity dynamics, dynamic similarity, laminar flows, and an introduction to waves and instability. Students should leave this course with a solid foundation in fluid dynamics, possessing a conceptual and mathematically rigorous understanding of the fundamental conservation laws for fluids and some basic applications of them. Together, METEO 520 and METEO 521 (Dynamic Meteorology) make up the core dynamics curriculum for graduate students of meteorology.
Data assimilation (DA) is the process of finding the best estimate of the state and associated uncertainty by combining all available information including model forecasts and observations and their respective uncertainties. DA is best known for producing accurate initial conditions for numerical weather prediction (NWP) models, but has been recently adopted for state and parameter estimation for a wide range of dynamical systems across many disciplines such as ocean, land, water, air quality, climate, ecosystem, and astrophysics. Taking advantages of improved observing networks, better forecast models, and high performing computing, there are two leading types of advanced approaches, namely variational data assimilation through minimization of a cost function, or ensemble-based data assimilation through a Kalman filter. Hybrid techniques, parameter estimation, predictability, and ensemble sensitivity methods will also be covered. Emphasis will be on applications to atmospheric science and numerical weather prediction, and the unique aspects of its observing systems, computer models, and predictability characteristics. The material in this course may be relevant to those in engineering, statistics, mathematics, hydrology, earth systems science, atmospheric science, and many other fields that seek to integrate information from observations and models.
Parameterization is the process by which important physical processes that cannot be resolved explicitly in a numerical model are represented. Examples include the transfer of shortwave radiation through the atmosphere, and the formation of cloud droplets, both of which occur on the molecular scale. As numerical models have grid spacing of hundreds of meters, molecular processes are not resolved explicitly in current models and so must be parameterized. A parameterization scheme is a representation of our understanding of the physical process as related to the available model variables, such that one can estimate how the behaviors of these important sub-grid physical processes influence the available model variables. In this way, sub-grid scale physical processes are included in models even when they cannot be explicitly represented. The most common parameterization schemes used in numerical models of the atmosphere will be discussed, including land and ocean surface, planetary boundary layer, convection, microphysics, radiation, cloud cover, and orographic drag. Emphasis is placed upon understanding the basic approaches to parameterization and how the differences in approaches influence the resulting behaviors.
Advanced treatment of thermodynamic principles as they relate to atmospheric cloud physics, radiation and dynamics.

This course provides graduate and advanced undergraduate students in the sciences and engineering an overview of the circulation of the ocean and the theories used to explain it. The focus is on the large-scale circulation driven by winds, buoyancy, and tidal forces. The course will also cover the distributions of temperature and salinity in the ocean, the surface ocean mixed layer, mesoscale eddies, and internal waves.
The atmospheric boundary layer is the layer of the atmosphere that is in frequent contact with the surface of the earth. It is the layer where life exists, and which mediates exchanges of energy, momentum, and chemicals between the earth's surface and the atmosphere. The scales of motion in the atmospheric boundary layer, because of the presence of the earth's surface, are small compared to the rest of the atmosphere. The dynamics, therefore, differ from those found in the 'free' atmosphere. This course describes the physical properties of the layer of the earth's atmosphere that is in frequent contact with the earth's surface, the atmospheric boundary layer. The course includes a descriptive overview of this layer using observations, then presents the governing equations and common simplifications used to describe the boundary layer. Conservation of mass, energy, and momentum, are covered. A core principle is the decomposition of the governing equations into a mean state and turbulent components, and the challenges introduced by this decomposition. The concepts of eddy diffusivity and closure methods are motivated by this challenge. These principles and governing equations are used to understand the typical evolution of the atmospheric boundary layer as a function of time of day. Convective and stable boundary layer conditions are contrasted. The contrasting conditions are linked to changes in the exchange of energy, momentum and water vapor at the earth's surface. The fundamentals of plume dispersion are described and tested. A simple numerical model of the atmospheric boundary layer is discussed and applied to atmospheric data. Stability conditions in the atmosphere are further explored using the equation for turbulent kinetic energy. Parameters describing the turbulence state of the surface layer and boundary layer, including the Obukhov length, friction velocity, convective velocity scale, and Richardson number, are discussed and applied to typical boundary layer conditions and observations. Similarity theory is discussed as a means of describing turbulent properties of the atmospheric boundary layer as a function of stability conditions. Monin-Obukhov similarity theory for the surface layer is applied to atmospheric observations. Additional common atmospheric boundary layer states are described, including cloud topped boundary layers, marine boundary layers, and boundary layers in heterogeneous terrain. Observational, measurement and numerical methods are presented and used in class assignments.
Successful science communication is critical to all aspects of meteorology, including research, operations, broadcast, and private industry, though scientific literature reveals the wide range of challenges to successful science communication. In this course, students learn primary modes of communication employed by atmospheric scientists, with emphasis on deterministic and probabilistic weather forecasts, global and regional climate projections, and examine their effectiveness. The course builds on this foundation to evaluate the institutional, social, behavioral, political, economic barriers to successful atmospheric science communication and quantify the impact of these challenges on scientific advancements and public responsiveness. Students will learn fundamentals in cognitive versus emotional empathy, communicative responsiveness, prosocial behavior, apply these concepts to the atmospheric sciences, and make inferences about how an individual's or society's perspective impacts decision making behavior.
This course focuses on one of the most challenging environmental issues of our era, the accumulation of carbon dioxide (CO2) and methane (CH4) in our atmosphere due to human modification of the global carbon cycle. We will study the processes, terrestrial, oceanic, atmospheric, and anthropogenic, that govern the sources and sinks of carbon into and out of the global atmosphere, and will study the methods used to quantify the carbon cycle. The primary focus is on the recent past (industrial era) and near-future (~100 years), when carbon cycle management decisions will play a critical role in climate change. The course starts with a review of global atmospheric CO2 and CH4 trends during the industrial era, and examines how atmospheric data inform our understanding of the global carbon cycle. The course then studies contemporary terrestrial biosphere, marine, and anthropogenic processes governing the carbon cycle. The paleorecord of the carbon cycle is reviewed, including glacial / interglacial cycles. Carbon cycle predictions and projections, including options for human management of the carbon cycle, are presented and evaluated. Ethical and economic factors, in addition to physical and biological processes, are considered. The course is appropriate for graduate students or advanced undergraduates with a sound background in quantitative sciences or engineering. The course is suitable for students from a wide variety of degree programs across the university.
Climate Dynamics delves into the fundamental processes that control the earth's climate of the past, present, and future. Fundamentals are developed from concepts of basic dynamic meteorology, radiative transfer, and thermodynamics. The surface energy and hydrologic budgets, and the atmospheric and oceanic circulation are covered. The cryosphere and its interactions with the atmosphere are also discussed. A survey of the earth's climate through geologic history is also explored. The concepts developed in this course are applied to the topic of anthropogenic climate change and how various aspects of the climate system could be influenced by global mean, long-term warming.

METEO 801Understanding Weather Forecasting for Educators3
Fundamental principles of synoptic and physical meteorology, remote sensing and data analysis in the setting of mid-latitude weather forecasting. METEO 801 Understanding Weather Forecasting for Educators (3) Never before has the quantity of available weather information so far exceeded the quality of the public's understanding of atmospheric science. METEO 801 aims to help correct this imbalance by helping secondary teachers to develop the knowledge and skills they need to become critical consumers of weather information and to, in turn, help their own students to do the same. Students who successfully complete METEO 801 will be able to apply knowledge of fundamental concepts of atmospheric science to discriminate between reliable and unreliable weather forecasts, to explain what makes one forecast better than another, and to teach these same concepts and applications to secondary school students. To ensure that students develop the knowledge and skills required to critically assess public weather forecasts, METEO 801 will provide an apprentice-training environment that will encourage students to learn forecast mid-latitude weather themselves. They will discover that weather forecasting involves sophisticated data analysis techniques, a thorough understanding of atmospheric science, and strong verbal and graphic communication skills. METEO 801 will combine digital video, audio, simulation models, virtual field trips to on-line weather data resources, text, and interactive quizzes that provide instantaneous feedback. The course will provide unprecedented access to one of the world's most distinguished meteorology programs. METEO 801 students will be granted licenses to use the courseware developed for this course in their own secondary classrooms. The overarching goal of the course is to help secondary science teachers become informed, critical consumers of the weather information they rely upon every day and to be able to effectively convey their knowledge to their students as part of an Earth science curriculum. Students will be required to complete weekly assignments. There are 12 lessons in METEO 801. Each lesson contains interactive exercises, links, animations, movies, and novel explanations of the basic scientific principles of how the atmosphere works. At the end of each Lesson, students will take an open-book "Promotion Quiz" that allows them to improve their status as an apprentice forecaster. In addition to Promotion Quizzes and weekly assignments on the course discussion board, students will be assigned four projects throughout the semester. Projects are also open book but require you to apply the principles students have learned to past case studies of storms and specific weather patterns.
METEO 802Fundamentals of Tropical Forecasting for Educators3
Applying atmospheric principles to the tropics, with an emphasis on the development, structure, prediction, and destructive impact of hurricanes. METEO 802 Fundamentals of Tropical Forecasting for Educators (3) Worldwide, approximately 80 tropical cyclones develop each year. This global annual average of tropical cyclones is small in comparison to the thousands of low-pressure systems that routinely parade across the middle latitudes each year. Yet tropical storms and hurricanes garner far greater attention from meteorologists and the media. The obvious reason for this lopsided focus is that tropical cyclones can inflict great devastation to life and property. To ensure that students develop the knowledge and skills required to critically assess weather forecasts issues by the National Hurricane Center, METEO 802 provides, like METEO 801, an apprentice-training environment. Under the tutelage of professional weather forecasters, students, in their role as apprentices, work toward the goal of creating their own tropical-weather forecasts. In the process, students in METEO 802 learn about the pitfalls of forecasting the tracks and intensities of tropical storms and hurricanes as they actively work with output from sophisticated numerical models available on the Internet. Moreover, successful students apply their knowledge of the fundamental concepts of atmospheric science in order to competently evaluate forecasts issues by the National Hurricane Center in Miami and the Joint Typhoon Warning Center in Honolulu. Students also gain a broad perspective of the general weather and oceanic patterns in the tropics. For example, students learn about El Nino and La Nina. In the process, they discover the El Nino and La Nina are not to blame for every unusual weather even that occurs anywhere in the world. To facilitate the learning objectives, METEO 802 includes the use of digital video, audio, simulation models, virtual field trips to on-line resources for weather data, text, and interactive quizzes that provide timely feedback. The course will provide unprecedented access to one of the world's most distinguished meteorology programs. METEO 802 students will be granted licenses to use the courseware developed for this course in their own secondary classrooms. One of the primary objectives of METEO 802 is to give secondary science teachers a working knowledge of hurricanes and tropical storms so that they can become critical weather consumers and to be able to effectively convey their knowledge to their students as part of an Earth science curriculum. Students will be required to complete weekly assignments. There are 12 lessons in METEO 802. Each lesson contains interactive exercises, links, animations, movies, and novel explanations of the basic scientific principles of how the atmosphere works. To demonstrate their mastery of the learning objectives, students complete automated online quizzes actively engage in online discussion groups focusing on real-time weather, and publish, to a person "e-portfolio," three comprehensive projects that explore timely case studies related to weather forecasting. The e-portfolio takes the form of a Web site. In addition to posting their work to their e-portfolio, students also use the space to reflect on their learning. By using their Penn State personal Web space to host their e-portfolios, students are able to share their work not only with program faculty and students, but also with external audiences, including potential employers.
METEO 803Fundamentals of Mesoscale Weather Forecasting for Educators3
Applying atmospheric principles to small-scale weather systems, with an emphasis on the conceptual modeling and short-range prediction of severe thunderstorms. METEO 803 Fundamentals of Mesoscale Weather Forecasting for Educators (3) When outbreaks of severe weather occur, dire warnings for tornadoes, large hail or damaging straight-line winds urgently scroll across the bottoms of television screens. Simultaneously, television weathercaster's warn viewers to "take cover immediately." Yet, because of the limited spatial and time scales of severe thunderstorms, the areas affected by tornadoes, large hail and damaging straight-line winds often turns out to be relatively small (sometimes as small as a tenth of one percent of the original "watch area"). There is no doubt that people should be prepared to take definitive action to protect their lives and the lives of their families when outbreaks of severe weather occur. But the overall impression that entire counties or cities will be destroyed by severe weather can be, and frequently is, misleading. To ensure that students develop the knowledge and skills required to critically assess public weather forecasts, METEO 803 provides an apprentice training environment that guides students, under the tutelage of professional weather forecasters, to actively learn how to create their own mesoscale-weather forecasts. In the process, METEO 803 reinforces the notion that weather forecasting involves sophisticated techniques of data analysis and a thorough understanding of atmospheric science. METEO 803 also stresses that the clear communication of the forecast requires strong verbal and graphic communication skills. Using conceptual models and real-time radar and satellite imagery in concert with output from numerical models designed specifically for mesoscale forecasting, students predict severe weather on time scales of a few hours to one day. For example, students are required to choose a tornado "watch-box" issued by the Storm Prediction Center (SPC) in Norman, Oklahoma, and then to evaluate the forecast (and forecast verification) in the setting of a litany of scientifically sophisticated tools on SPC's Web site. In effect, students will mirror the process that professional forecasters follow to create such high-profile forecasts. For more general outlooks that identify regions where there is a potential for severe weather (time scales of one to two days), students will use output from the numerical models that were introduced in METEO 801 to identify the areas likely to be at risk for severe weather. To facilitate the learning objectives, METEO 803 includes the use of digital video, audio, simulation models, virtual field trips to on-line resources for weather data, text, and interactive quizzes that provide timely feedback. The course will provide unprecedented access to one of the world's most distinguished meteorology programs. METEO 803 students will be granted licenses to use the courseware developed for this course in their own secondary classrooms. One of the primary goals of METEO 803 is to give secondary science teachers a scientifically grounded perspective of the spatial and time scales of typical outbreaks of severe weather and other events associated with mesoscale weather systems. In the process, students become better weather consumers and to be able to effectively convey their knowledge to their students as part of an Earth science curriculum. To gain such insights, students learn conceptual models of the life cycles of severe thunderstorms and then apply them in real-time outbreaks of severe weather. In the final analysis, students are able to more accurately weigh the information being disseminated by the media and the Storm Prediction Center in Norman, Oklahoma. Students will be required to complete weekly assignments. There are 8 lessons in METEO 803. Each lesson contains interactive exercises, links, animations, movies, and novel explanations of the basic scientific principles of how the atmosphere works. To demonstrate their mastery of the learning objectives, students complete automated online quizzes, actively engage in online discussion groups focusing on real-time weather, and publish, to a personal "e-portfolio," three comprehensive projects that explore timely case studies related to mesoscale weather forecasting. The e-portfolio takes the form of a Web site. In addition to posting their work to their e-portfolio, students also use the space to reflect on their learning. By using their Penn State personal Web space to host their e-portfolios, students are able to share their work not only with program faculty and students, but also with external audiences, including potential employers.
Anticipating weather events first requires an understanding of typical (or expected) conditions at a particular site. Such climatologies are constructed primarily from historical observations but may also include numerically derived forecasts and analyses. In this course, students will learn a variety of methods for accessing appropriate weather and climate datasets available from government and research institutions. Working with very large datasets in a computationally efficient manner will be stressed, as will consideration of factors that affect data reliability. Students will be encouraged to consider numerous possibilities for presenting weather and climate data with a minimum of quantitative analysis. In addition, numerous examples and case studies will augment discussions on such topics as numerical reanalysis datasets, self-describing archives, and typical problems encountered with environmental observations. Finally, students will learn to construct a site-specific or regional climatology and to communicate a qualitative analysis of those data to others.
