Seasonal hydrological prediction in Great Britain – an assessment
… the study evaluates river flow prediction using climate model output to drive a rainfall-runoff model in the Dyfi basin, Wales. Results show that climate model precipitation can not skilfully simulate Dyfi discharge. When a downscaling process is employed to generate precipitation time series, …

The UK wind regime - Observational trends and extreme event analysis and modelling
Abstract The UK has one of the most variable wind climates; NW Europe as a whole is a challenging region for forecast- and climate-modelling alike. In Europe, strong winds within extra-tropical cyclones (ETCs) remain on average the most economically significant weather peril when averaged over …

Orographic Gravity Wave Drag and the Large Scale Atmospheric Circulation
The need for accurate climate modelling demands an understanding of the physical processes in the atmosphere in order to improve model capability. Much of this modelling is concerned with the general circulation, which is affected by orographic gravity waves and the drag force that they exert on …

The climatic significance of tropical forest edges and their representation in global climate models
An emerging theme in global climate modelling is whether land covers created in the clearance of tropical humid forests influence water exchange between remnant forest patches and the atmosphere, and, if so, how this affects regional and global water exchange. Fieldwork presented in this thesis …
