Welcome to Global Atmospheric Circulations, a course on the general circulation of the atmosphere taught by Professor Richard Grotjahn at UC Davis. Please select topics from the menu below:
Note: This year there is one fewer lecture period. There will be some adjustment of subjects shown below for a prior offering.
Course information for Winter 2000, 2006, 2008, 2010, 2014, 2016, 2019:

Course (older) Textbook:
e. Reading Materials
A new book is in preparation: Understanding the General Circulation, a.k.a. 'Grotjahn (2020)'. Below are reading materials from Grotjahn 2020 at present. (All are draft documents, still being revised)
These documents replace or supplement the readings from Grotjahn 1993.

II. Web products for course lectures:
b. Summary of Momentum Cycle in the Zonal Mean Atmosphere. A Table that shows the source, transport, then sink of momentum in the atmosphere as 8 distinct steps. A schematic chart in included.
c. Summary of Energy Flow in the Zonal Mean Atmosphere. A Table that makes connections between how the heat and momentum (as APE and KE) flow in the atmosphere.
