Research Interests

Nicolas' research interests are in all aspects of meteorology and climatology. The study of the atmosphere inevitably involves an understanding of other components of the global environment, which for Nicolas has been primarily the cryosphere.  Much of his research has focused on the interactions of the atmosphere with snow and ice surfaces in the high and mid-latitudes, as well as on a number of high mountains in the tropics (e.g. Kilimanjaro). Nicolas is also interested in the impacts of atmospheric processes on human behaviour, in particular air pollution meteorology, utilizing wind for energy through turbine development and issues related to climate change on local to global scales.  The research that Nicolas undertakes is dependent on a combination of field data, remote sensing observations and modelling.
