(CSU, 1976-1987, PhD, 1986) Badger (UW professor since 1987) Teacher and Research Meteorologist specializing in basic understanding of convective weather systems through explicit mathematical modeling of physical processes

5. Course Goals Develop a basic understanding of the Earth’s atmosphere including the role of weather and the legacy of climate Develop a basic working knowledge of how to diagnose the current state and predict the future state of the atmosphere from online resources Develop skills to understand, observe and anticipate severe and unusual weather and climate and embrace the awe that it endears

7. Grading for 101 Lecture 75% Discussion/Laboratory 25%

8. Basic Lecture Structure 10-15 minute discussion of current weather, pointing to applications of the current topic…on special occasions, this discussion may take longer or all of the class time Answer questions from class regarding reading assignment Lecture designed to expand and embellish selected topics from reading or introduce topics not found in reading

9. Text Book Severe and Hazardous Weather An Introduction to High Impact Meteorology (4 th Edition) By Robert M Rauber, John Walsh, Donna Charlevoix Kendall/Hunt Publishing Co., Dubuque, Iowa

10. Material for Which You Will Responsible The class is divided into 6 subject areas for which lectures are built. The lecture subject each day will appear in the syllabus. Dates of when subjects will be covered are estimated in the syllabus now, but will be modified as we move ahead or behind the schedule Specific text book chapters will be assigned in the syllabus. You are expected to read this material before class. Lectures will be designed to discuss text book material, but will not cover all of the material presented in the text book. You still are responsible for material not covered unless I specifically say that you are not responsible for certain material. It is your responsibility to ask questions to clarify subjects that you do not understand. Generally, homework questions will be a good guide to the questions appearing on the tests.

11. Homework A homework will be assigned every other week The assignment will be listed on the Lecture Slides available on line Assignments will consist of: –Problems in the text –Problems based on Lecture material Homework will be handed in electronically

17. Introducing to Weather and Climate Radiation from the sun (mostly in the form of visible light) shines on the earth and for the most part passes through the atmosphere on to the surface Sun shining on surface (2/3 water) has two effects: –Causes water to evaporate –Heats the surface, and heat is conducted into the air

18. Introducing to Weather and Climate In order for the planet to maintain an equilibrium temperature, the Earth must radiate to space the same amount of heat that it absorbs from the sun The Earth radiates heat from everywhere The planet heats and moistens only where the sun shines Circulations must form to move heat and moisture around, thus causing weather
