Matt Brown

Graduate student (DTP)

Academic Profile

I completed an MMet (equivalent to an MSci) in Meteorology and Climate at Reading, graduating with First class honours. My dissertation was looking at how uncertainty in measured rainfall translates to soil moisture in land surface models, to ultimately aid the rollout of weather index insurance to farmers in Africa. I spent some time over the subsequent summer working at Reading in the TAMSAT (Tropical Applications of Meteorology using SATellite data) group on developing a drought prediction scheme for Africa using information on the state of the land surface, before arriving in Oxford to start on the DTP in Environmental Research.

Current Research

At Oxford I have shifted focus to the upper atmosphere, where I am investigating how the northern hemisphere polar vortex, a strong jet stream that surrounds the pole during winter, is affected by the wind pattern over the equator. The winds over the equator are influenced by many things themselves, including the 11-year solar cycle - a variation in the amount of ultraviolet light received by the upper stratosphere. This research may have implications for seasonal predictability, in particular the winters of Northern Europe, and is carried out in conjunction with the Met Office as a CASE partnership.
