Homepage for Ph536, Atmospheric Convection

This is the homepage for a graduate course in the physics of atmospheric convection. We will cover the dynamics, thermodynamics, and microphysics of convection, as well as its interaction with the rest of the atmosphere.

Some notes from the continuum mechanics course may be a useful supplement for the first few weeks of lectures.

Expectations and grading

Class time will be split between lectures and problem solution. You will also be asked to write a paper on some aspect of atmospheric convection. This will be presented orally near the end of the semester. The grading will be based 70% on problem solutions and 30% on the paper.

Paper schedule

• Choice of paper topic due: Thu 3 Feb.
• First draft due: Thu 24 Mar.
• Oral presentations: 5 May.
• Final draft due: Thu 28 Apr.

Assignments

Assignments will be announced in class and on the web. A few days after an assignment is made, we will discuss the problems in class. Shortly thereafter written versions will be due.
