Course Meeting Time and Location:
CLASS: Monday, Wednesday and Friday, 9:00-9:50am National Weather Center, Rm. 5600
This course provides fundamentals and principles for understanding of the physical states and processes of clouds and precipitation as well as atmospheric electricity and optics. Specific topics that will be covered are as follows:
Review of thermodynamics Aerosols and nucleation Condensation growth Collision and coalescence
In-situ measurements and results Radar observation and estimation
Electrostatics Electromagnetic wave Thunderstorm charging Lightening
Reflection and refraction Optical phenomena
This course provides an overview of cloud and precipitation processes including: the role of aerosols in cloud droplet and ice nucleation; development and application of the Clausius-Clapeyron equation for phase changes; the transformation of cloud particles into rain, snow, and hail by diffusion, collision and coalescence, and aggregation; fundamentals of cloud microphysics parameterization; cloud electrification and lightning; optical phenomena, and basic understanding of weather radars.
Students are expected to understand and use the physical meanings of state parameters, and the relationship between physical states and processes in the atmosphere. Skills obtained from the
course will be assessed through homework assignments, quizzes, and examinations.

I believe that teaching at all levels has the common goals of disseminating knowledge and training students to use their knowledge to improve society. With each step forward in a student’s education, the ability to balance various aspects of their studies becomes more and more important until, at the college level, it is not merely an advantage, but a necessity. As such, in this class, we’ll emphasize several balances: those between physical concepts and mathematical derivations, between theory and experimentation, between learning and thinking, between thinking and doing, between attending classes and doing assignments.
Consider telling students what you expect them to do, both in class and outside of class. Although some expectations may seem self-evident, you are more likely to have students meet your expectations when you state them explicitly. Students have a better chance of being successful when they know precisely what you expect. Instructors usually include their expectations regarding attendance, class workload, when students should complete the assigned readings, and participation.
Homework problems (after every chapter): 20%
Quizzes (every two chapters): 10%
Midterm examination (3nd week of March): 30%
Final examination (5/8/2018, 8am-10am): 40%
Cheating is strictly prohibited at the University of Oklahoma, because it devalues the degree you are working hard to get. As a member of the OU community it is your responsibility to protect your educational investment by knowing and following the rules. For specific definitions on what constitutes cheating, review the Student’s Guide to Academic Integrity at http://integrity.ou.edu/students_guide.html.
To be successful in this class, all work on exams and quizzes must be yours and yours alone.
