Module Overview

This module uses applied mathematics to describe the fluid mechanics of the atmosphere.

Prerequisites/Co-requisites

MAT2007 ODEs, MAT2011 (Linear PDEs); Desirable – MAT2010 (Fluid Dynamics). (A good knowledge of Level 1 vector algebra and calculus will be assumed.)

Module Aims

The aim of this module is to introduce the student to the relevant topics in dynamical meteorology, and to the basics of the numerical modelling that underpins modern numerical weather prediction.

Learning Outcomes

By the end of the course students should

Understand the basic equations of fluid motion as used in weather prediction.

Understand the basic approximate models based on balance: quasi-geostrophic theory and semi-geostrophic theory;

Understand the basics of barotropic and baroclinic waves and their stability.

Module Content

The module starts with an overview of the weather prediction as it is done today at the

Mathematics plays a central role in the development and analysis of models for weather prediction, and this module will introduce the student to a range of mathematical topics including

· The Lagrangian and Eulerian descriptions of fluid motion and their application to the analysis of weather systems;

· Governing equations, including the effects of rotation and stratification, geostrophic and hydrostatic balance;

· The role of quasi-geostrophic theory in meteorology;

· Vorticity dynamics, potential vorticity;

· Linear barotropic waves (Kelvin, inertia-gravity and Rossby waves);
· Barotropic and baroclinic instability.

Semi-geostrophic theory
