# Dynamics of the Atmosphere and Ocean

## Objectives and Content

Objectives:

The course presents the governing equations and their application to various phenomena in geophysical fluid dynamics. Topics in atmospheric sciences and oceanography are studied using theory, demonstrations and exercises.

Content:

Main topics are geostrophy; the effect of friction in the surface and bottom boundary layer (Ekman dynamics); waves in homogeneous and stratified fluids, with and without rotation effects; potential vorticity; the quasi-geostrophic framework; and barotropic and baroclinic instability.

## Learning Outcomes

On completion of the course the student should demonstrate the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge:

The student

• understands the governing equations of large-scale motion on a rotating planet
• understands steady state and balanced flows in the atmosphere and ocean
• understands the basics of waves in the atmosphere and ocean
• understands the basic principles of barotropic and baroclinic instability

## Place of Instruction

Bergen
Required Previous Knowledge

Principles of meteorology and/or oceanogarphy in addition to basic knowledge in maths and physics (mechanics) or equivalent to GEOF110 and MAT212.

This is a theoretical course which requires a solid mathematical background. To follow the course you must be familiar with (and be able to use) concepts like differential equations, partial derivatives, curl, the equation of motion in a rotating frame of reference, the Coriolis force, geostrophic flow, Ekman dynamics. You also need to have basic programming skills in e.g. Matlab, Python or similar.
