At its peak extent, snow can cover more than 40% of the Northern Hemisphere land surface, greatly affecting surface exchange processes, and hence global climate. Snow is one of the most dynamic surface types and its distinct physical properties imply that it requires special attention when modelling short-term weather conditions and long-term climate. Natural hazards such as avalanches, reduced visibility from blowing snow, and snowmelt-induced flooding all necessitate the precise monitoring and modelling of snowpack evolution and attendant atmospheric conditions. It is therefore critical that we develop a better understanding of snow accumulation/ablation processes and their impacts on climate. |
