 I completed my undergraduate course at Exeter in 2010 and am now studying for a PhD supervised by Frank Kwasniok and John Thuburn looking at the stability and dynamics of the polar vortex.

A polar vortex is a persistent, large-scale cyclone located near one or both of the Earth's geographic poles. The polar vortices are located in the middle and upper troposphere and the stratosphere. The breakdown of the polar vortex is an extreme event of particular importance known as a sudden stratospheric warming; here the vortex completely breaks down and an associated warming of 30-50 K over a few days can occur. The PhD project aims at studying and understanding the dynamics of the polar vortex under large-scale perturbations using conceptual models from geophysical fluid dynamics. The project combines data analysis, analytical stability calculations and experiments with numerical models.
