# Clouds and Climate

## The Romps Group at the University of California, Berkeley

This course covers the processes that determine the structure and circulation of Earth's atmosphere. The approach of this course is deductive: the properties and behavior of Earth's atmosphere will be derived from the laws of physics and fluid dynamics. Topics will include the governing laws of fluid dynamics, dry and moist thermodynamics, radiative transfer, cloud microphysics, geostrophic flow, quasigeostrophic motion, atmospheric waves, and baroclinic instability.
