Learning Outcomes

Upon successful completion of this course students should be able to:

Understand the physics governing the dynamics of atmospheres and oceans, including many observed phenomena such as extratropical storms, hurricanes, jet-streams, boundary currents (e.g., the gulf stream), oceanic and atmospheric waves meridional circulation cells, and climate on other planets.
