Arctic cyclone characteristics in shaping subseasonal-to-seasonal air temperature and sea ice changes in the context of Siberian-Alaskan Arctic atmosphere-ocean interactions
Abstract
Funds are provided to evaluate the role of Arctic cyclones and their interactions with the ocean in shaping subseasonal-to-seasonal(S2S) surface air temperature (SAT) and sea ice anomalies during the melt season. Special focus is directed on the rapid sea ice change region of the Siberian-Alaskan Arctic (SAA), which is comprised of the East Siberian Sea, Chukchi Sea, and Beaufort Sea. The project will evaluate how SIC conditions and associated ocean-atmosphere interactions affect the frequency, intensity, duration, andtracks of Arctic cyclones and how these modified storms subsequently feed back on ice conditions primarily through thermodynamic forcing. The project team will use observational datasets and statistical techniques to evaluate linkages between Arctic cyclone characteristics and S2S SAT and sea ice variability. These analyses will motivate a series of downscaled climate model experiments designed in an effort to advance understanding of how cyclones and their associated physical processes cumulatively impact S2S SAT and sea ice in the SAA region.
