Large-scale atmospheric dynamics, such as monsoons and Hadley cell dynamics, are important in our understanding of global climate and in tropical-extratropical interaction. Therefore, my research work in this area largely focuses on topics that are much more broad in the spatial scale, such as the nature of the zonally-varying response to local and regional signals such as ENSO. On a broader scale, I am also interested in understanding the interaction between the Hadley cell circulation and the climate of the mid-latitudes.

Many previous studies have investigated the impact that global warming and ENSO have on the outer edge of the Hadley cell and the location of mid-latitude storms. However, most of these studies analyse only the zonally averaged response of the circulation, which can obscure regional responses. Therefore we aim to:
- Study the global response of the subtropical jets and mid-latitude storms to ENSO using reanalysis datasets and their asymmetrical response
- See if these asymmetries can be modelled in idealised GCMs by the addition of localised heat fluxes at the equator
