Profile

I am a PhD candidate based in the School of Earth and Environment at the University of Leeds. My research seeks to evaluate the meridional circulation of the stratosphere, and its projected changes under increasing greenhouse gas (GHG) concentrations. That includes designing and implementing experiments with various versions of the UK Met Office (UM) global climate model in order to investigate how Brewer Dobson circulation trends depend on the representation of physical climate processes.

Project outline

Climate models consistently simulate an increase in the strength of the Brewer-Dobson circulation (BDC) under climate change, but many fundamental questions remain about the mechanisms for this response and quantitative constraints on the trends simulated in models. Furthermore, the circulation is poorly constrained by observations since it must be indirectly inferred from atmospheric tracers, which presents further challenges for understanding the BDC and its representation in models. It is therefore important to understand how, and why, the BDC may change in response to current and future human activities, such as emissions of GHGs.
