## Objectives and Content

Objectives

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

Content

Main topics are geostrophy and wind-induced Ekman currents; wave equations for gravity waves in homogeneous and stratified fluids, in the presence and absence of the Coriolis effect; quasi-geostrophic frameworks for planetary and topographic Rossby waves; 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 basic principles of large-scale motion on a rotating planet
• understands the governing equations of various phenomena in geophysical fluid dynamics
• understands the basics of waves in the atmosphere and ocean
• understands the basics of steady state motions in the atmosphere and ocean
• understands the basics principles of barotropic and baroclinic instability

Skills

The student

• can scale and simplify the governing equations for solving basic dynamical problems
• can formulate and solve problems in a geostrophic framework
• can formulate and apply wave theory to surface and internal waves
• can formulate and use Ekman theory to calculate responses to various scenarios of wind forcing
• can write a lab report

General competence

The student

• is able to discuss basic governing equations in dynamical meteorology and oceanography
• is able to derive, scale and simplify the governing equations
• is able to present and discuss dynamical phenonema in the atmosphere and ocean

## 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.
