Lie in the field of hydroclimatology, and particularly in understanding large-scale climate variation and how this is linked to changes in river flow. I have worked both to develop better understanding of how present day climate variation leads to changes in river flow, and of the uncertainty associated with how river flow may respond under scenarios of climate change. This has involved:
(i) statistical analyses of historical river flow variation, with particular focus on the North Atlantic region, the role of atmospheric circulation patterns such as the North Atlantic Oscillation, and the combined ocean-atmosphere conditions than can lead to the development of hydrological drought
(i) offline coupling of catchment-scale hydrological models with climate model output, focussing on understanding the role of emissions, climate model and hydrological model-based uncertainty in shaping projections of 21st century hydrological change and associated implications for water resources. These interests have largely been pursued through the Global Scale Impacts of Climate Change project within the NERC-funded QUEST programme
