# PHYC/OCEA 4411/5411 - Atmospheric Dynamics I

Atmospheric Dynamics describes the fluid motions of the atmosphere in terms of fundamental physical laws using the language of mathematics. Part I deals mostly with establishing basic principles and deriving the governing equations, whereas Part II focuses on applications, including weather.

## Final Exam

Friday, Dec 11, 12 - 3 PM @ Dalplex

The final exam will cover all of the material from the first class up to the end of the lecture on "Rotation in Thunderstorms". No calculators or other electronic devices are permitted.

## Class Evaluations

Class evaluations are to be completed online before midnight on 8 December 2009. You should have received an email from the Department about this. If not, please let me know as soon as possible.
