This module is not approved as an Elective

Module summary

This module is concerned with the mathematical modelling of various phenomena observed in geophysical flows (i.e., those in the Earth's atmosphere and ocean, and upon the planetary surface). The focus is on waves and flowing currents, and how these are related to vertical density variations within the fluid and to the rotation of the Earth.

Objectives

For students with a basic training in mathematical fluid dynamics, this module will provide the necessary
additional knowledge and mathematical techniques to understand and model geophysical flows. These ideas
are central to further study in environmental and climate sciences.

Learning outcomes

- An awareness of various flow regimes in geophysical fluid dynamics;
- An understanding of the underlying physical processes that lead to these flows;
- The ability to construct and analyse idealized mathematical models of these processes;
- An appreciation of the relevance and limitations of these mathematical models.

Syllabus

- Governing equations of motion for rotating, stratified flow. Vorticity.
- Some effects of stratification: buoyancy frequency, gravity waves.
- Some effects of rotation: geostrophic flow, Taylor–Proudman theorem, Ekman layers.
- Rossby waves. Linear wave theory.
- Shallow-water flows: inertia-gravity waves, the wind-driven ocean circulation, nonlinear solutions.
- Viscous geophysical flows.
- 2D turbulence: conservation laws, inertial ranges.
