Objectives and Content
The course builds on GEOF110 (Introduction to Atmospheric and Oceanic Dynamics). The governing equations will be examined and scaled for various phenomena in geophysical fluid dynamics. The effect of Earth's rotation will be introduced via the dynamical equations. Geostrophic and wind-induced Ekman currents will be discussed. Furthermore, the wave equations for gravity waves as well as potential vorticity waves will be studied and analysed. In addition, barotropic instabitliy and baroclinic instability in the framework of the quasi-geostrophic equations will be introduced.
After completing GEOF213 the student will be able to:
- describe and discuss the basic principles of large scale circulations on a rotating planet
- understand the basics of waves of the atmosphere and ocean
- scale and simplify the governing equations for solving basic dynamical problems
- formulate and solve problems in a quasi-geostrophic framework
- use Ekman theory to calculate various scenarios of wind forcing
- derive and use dispersion relations for gravity and potential vorticity waves
- apply the wave theory on surface and internal waves
- understand the principles of barotropic and baroclinic instability
