Description:This course provides an introduction to the fluid dynamics of the extratropical atmosphere. Our main objective is to derive a simplified set of equations that capture the dynamics on these scales, while providing a foundation for physical understanding. Potential vorticity provides a useful framework to link physical understanding of theory and observations. The simplified equations are applied to: Rossby-wave propagation, baroclinic and barotropic instability, and nonlinear dynamics (turbulence).
Prerequisites: ATMS509 or OCEAN 512.
