I'm an Associate Research Fellow working with Mat Collins on the Climate Science for Services Partnership: China Project (project lead Geoff Vallis). My work involves assessment of Tropical Pacific mean climate and El Niño Southern Oscillation feedbacks and teleconnections in coupled climate models. My work focusses on quantifying multi-model ensemble variations in climatology and ENSO-associated atmospheric and oceanic processes. Links between such biases improve understanding of coupled climate model shortcomings, thus aiding future model development.

 

My PhD work was also based at the University of Exeter and focussed on similar ENSO feedback assessment using the Bjerknes stability index, a metric incorporating a number of ocean-atmosphere feedbacks. This work was carried out using a HadCM3 perturbed-physics ensemble, rather than a multi-model ensemble, and also looked at ENSO feedback responses to a warming climate.
