The Role of Cyclone Activity in Snow Accumulation on Arctic Sea Ice
Identifying the mechanisms controlling the timing and magnitude of snow accumulation on sea ice is crucial for understanding snows net effect on the surface energy budget and sea-ice mass balance. Here, we analyze the role of cyclone activity on the seasonal buildup of snow on Arctic sea ice using m...
