The Changing Arctic Seas: Weather System Amplifiers?
Session ID#: 158221
Session Description:
Warming of the Arctic Ocean and overlying atmosphere has resulted in a profound decrease in sea ice, which has altered the sources, magnitudes, and timing of surface-to-atmosphere and atmosphere-to-surface turbulent and radiative fluxes. Extreme meteorological events, including compound events, appear to be emerging more frequently in conjunction with the decline of Arctic sea ice. The physical development of synoptic extremes has been linked to local and large-scale feedbacks as these weather systems entrain surface heat and moisture aloft while transiting “new” areas of open water in the marginal seas and broader Arctic (e.g., Arctic Ocean in 2012, Bering Sea during autumn 2018, and Barents Sea in winter 2018). Such modified weather systems can further amplify regional extreme events (e.g., coastal flooding and erosion), and impact the upper atmosphere, and/or affect downstream weather anomalies.
In this session, we invite talks that evaluate the role of sea-ice and upper-ocean conditions on Arctic weather patterns and processes. Case studies and composite approaches using an array of in-situ, satellite, reanalysis, and weather/climate model-derived products are welcome. Topics may include, but are not limited to, bi-directional investigations linking Arctic mesoscale and synoptic-scale weather anomalies to Arctic sea-air fluxes, compound extreme event development emanating from such interactions, and high-latitude thermal and hydrological extremes (e.g., rainfall, snowfall, rain-on-snow events, and drought) linked to rapidly evolving regional ice-ocean conditions and their propagating effects throughout the annual cycle.
