LAGRANGIAN FLUID DYNAMICS OF PLANET EARTH - 2018/9

Module code: MAT3048

Module Overview

Motivated by problems in meteorology and oceanography, this module applies a range of mathematical techniques to the characteristion of fluid flows. Geometry, vector calculus, differential equations, symmetry, dynamical systems theory, and analysis are all combined with fluid motion to produce a deeper understanding of atmosphere and ocean dynamics.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:
Understanding of fundamental concepts and ability to develop and apply them to a new context.
Subject knowledge through recall of key definitions, formulae and derivations.
Analytical ability through the solution of unseen problems in the test and examination.

Thus, the summative assessment for this module consists of:
One two hour examination at the end of the semester, worth 80% of the overall module mark
one fifty minute class test worth 20%

Formative assessment and feedback

Students receive written feedback via the marked class test. The solutions to the class tests are also reviewed in the lecture. Un-assessed courseworks are also assigned to the students, and a sketch of solutions to these are provided. Verbal feedback is provided during lectures and office hours.

Module aims

  • The module aims to cover the range of mathematics required to understand the dynamics of fluid motion in the context of meteorology and oceanographic flows on planet earth.

Overall student workload

Independent Study Hours: 117

Lecture Hours: 33

Methods of Teaching / Learning

Teaching is by lectures, 3 hours per week for 11 weeks. Lecture notes are provided. Learning takes place through lectures, exercises and class tests. Blackboards and whiteboards are used for real-time presentation. Supplementary notes provided via SurreyLearn. Periodic special lectures are devoted to discussion of example sheets.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
