Dean Walker


Dean is a postgraduate research student at the University of Leeds. He is supervised by Dr Cathryn Birch, Dr John Marsham, and Prof. Adam Scaife (UK Met Office). Dean's work involves predictions of rainfall over East Africa at seasonal timescales. Seasonal forecasting is vitally important in East Africa, as it allows forecast users time to prepare responses to large scale weather events such as region-wide droughts. Dean's work looks to evaluate the current state of seasonal forecasts over East Africa, both those generated within the region, such as the Greater Horn of Africa Climate Outlook Forum (GHACOF) forecasts, and dynamical model predictions from the UK Met Office's seasonal forecast system, GloSea. The work will then look to improve understanding of processes controlling seasonal rainfall variability, and their potential for predictability. 

Prior to moving to Leeds, Dean studied at the University of Warwick, gaining a Master's Degree in Mathematics and Physics. During this time he undertook research projects within soft matter physics, and ultrasonics.
