COURSE OBJECTIVES
Met 601 is the second part of a two-semester course series (MET 600 and MET 601) on Advanced Atmospheric Dynamics. The objectives of Met 600 and Met 601 are to provide a theoretical background in geophysical fluid dynamics and dynamic meteorology, to develop students' ability to quantitatively analyze atmospheric motion and understand the physics, and discuss current issues in tropical dynamics.

- Equatorial waves 2: Equatorial Rossby, inertial-gravity, and mixed Rossby-gravity waves
Part II Large-Scale Instability Theory
- The problem of quasi-geostrophic instability
- Necessary condition for the instability
- Energetics
- Baroclinic instability (1): Eady model
