Type of module:

Summary module description:
We will derive and analyse a number of numerical methods for solving the type of equations used in atmosphere and ocean modelling. Students will implement some of these methods using the Python programming language.

Aims:

The aim of this module is to familiarise the students with a range of concepts and techniques used in the numerical modelling of atmospheric and oceanic fluid flows.  This will include mathematical analysis, modelling and some good programming practices, code testing and version control.

Assessable learning outcomes:

By the end of this module students should be able to:

• Derive numerical schemes using Taylor series;

• Explain the concept of stability and perform a basic stability analysis;

• Implement and test the behaviour of numerical schemes using Python;

• Recognize sources of numerical error and derive and measure order of accuracy;

• Use Fourier series for analysing both numerical methods and climate data;

• Use functions and loops in Python and avoid code duplication;

• Use git version control software for collaboration;

• Have some knowledge about how code should be tested

Students will develop skills of working to deadlines and preparing clear, concise written reports.

Outline content:

The lecture content covers:

• Derive finite difference approximations using Taylor series;

• Differential equations with time and space derivatives;

• Techniques for solving the diffusion equation,the advection equation and the wave equation;

• Use of Fourier series:

• Python including use of functions and testing:

• Version control using git

The practical classes cover:

• Introduction to Python;

• Implementation of numerical schemes and demonstration of their behaviour.
