## 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.

## COURSE OUTLINE

### Part I Wave Theory (review)

- Equations for atmospheric motion and simplifications
- Poincare wave and Kelvin wave: Effects of side boundary
- Barotropic Rossby wave packet
- Energy propagation and reflection of Rossby wave packet
- Equatorial waves 1: General dispersion relation and equatorial Kelvin wave
- 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
- Baroclinic instability (2): Charney model

- Weakly nonlinear theory

### Part III Dynamics in the Tropics

- Scale analysis
- Cumulus parameterization
- Conditionally instability of the second kind
- Vertically propagating equatorial waves
- Quasi-biennial Oscillation
- Steady forced motion

### Part IV Some Topics in Climate Dynamics

- Rossby wave train and teleconnection
