Objectives | Outline | References | Grading


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.

  2. Poincare wave and Kelvin wave: Effects of side boundary
  3. Barotropic Rossby wave packet
  4. Energy propagation and reflection of Rossby wave packet
  5. Equatorial waves 1: General dispersion relation and equatorial Kelvin wave
  6. Equatorial waves 2: Equatorial Rossby, inertial-gravity, and mixed Rossby-gravity waves

Part II Large-Scale Instability Theory

  1. The problem of quasi-geostrophic instability
  2. Necessary condition for the instability
  3. Energetics
  4. Baroclinic instability (1): Eady model

Part III Dynamics in the Tropics

  1. Scale analysis
  2. Cumulus parameterization
