Study Time Outside of Class: About 7 hours per week


Purpose of Course:

  1. To review the basic concepts of thermodynamics and to apply these concepts to the atmosphere.

  2. To provide an introduction to the physical processes leading to the formation of clouds, rain, snow and thunderstorm electrification.

Course Outline:

Thermodynamics is a cornerstone of classical physics, and one of the great intellectual achievements of mankind. Its applications extend beyond physics, to chemistry, biology, engineering and economics.

Since this course does not assume any previous knowledge of thermodynamics, we will first discuss the basic principles of thermodynamics, including the First and Second Laws. We will then apply thermodynamic concepts to the earth's atmosphere. This will lead us to an understanding of how thermodynamic data, provided by the worldwide network of radiosondes, can be used in weather forecasts (e.g., of severe storms).

The last segment of the course will use thermodynamic principles to explain how clouds form. This will lead us to discussions of the formation of rain and snow, and the processes responsible for thunderstorm electrification.

Assignments:Homework is assigned and solutions are discussed in class each Friday.
