About This PhD Project

Project Description

Location: Streatham Campus, University of Exeter, EX4 4QJ

Project Description:
The Centre for Geophysical and Astrophysical Fluid Dynamics at Exeter is one of the leading research groups of its kind in the UK. Our research encompasses the Fluid Dynamics of Weather and Climate, Theoretical Fluid Dynamics, Astrophysical Fluid Dynamics, Solar-Terrestrial Plasmas and Space Weather. We invite applications to study for a fully-funded PhD starting in Sept 2016.

Industrial CASE joint UoE Met Office PhD studentship. The Gulf Stream plays an important role in the prediction of weather and climate throughout northern Europe.

1) Analysis of high resolution ocean model dynamics.

2) The development of new mathematical and numerical methods.

The Gulf Stream plays an important role in the prediction of weather and climate throughout northern Europe. Coarse resolution ocean models misrepresent the path of the Gulf Stream which leads to poor predictions for northern Europe. This project aims to improve the understanding of the dynamics of the Gulf Stream. This understanding will then be applied to develop new mathematical and numerical methods with the goal of improving the representation of the Gulf Stream in Nemo.

The first step in the PhD project will be to calculate dynamical diagnostics of the Gulf Stream path using models of in 1°, 1/4°, and 1/12° resolution. Depending on the results and the interests of the student, the PhD could develop in the following directions: in-depth investigation and interpretation of aspects of the vorticity dynamics, the theory and dynamics of western boundary currents in the presence of sloping bathymetry, assessment of the impact of alternative representations of momentum advection or physical parameterisations of eddy fluxes on the Gulf Stream path. The student will be encouraged to formulate and experiment with novel ideas in numerics, diagnostics, and theory for ocean physics and dynamics. Research questions to be addressed include: 1) What processes control the dynamics in the Gulf Stream extension? 2) What are the roles of mesoscale fluctuations in western boundary currents? 3) How do mesoscale fluctuations strengthen the interactions with bathymetry?

Academic Entry Requirements:
Applicants should have or expect to achieve at least a 2:1 Honours degree, or equivalent, in Maths, Physics, Natural Sciences or other numerate discipline. Interviews will take place 9th March 2016.
