A52B:
Arctic Energy Balance and Relevant Atmosphere and Surface Processes: Current Understanding and Challenges I


Submit an Abstract to this Session


Session ID#: 58121

Session Description:
The Arctic is experiencing more rapid changes than anywhere else on Earth with far-reaching socioeconomic implications. Arctic climate variations in the last decade are strong indicators of the important yet delicate coupling between atmospheric and surface processes in the region. Projected Arctic responses to rising CO2 by state-of-the-art earth system models still exhibit large spreads in key parameters like temperature, sea ice loss, and ice sheet melt. This spread partly stems from an incomplete understanding of the processes that affect energy flows in the Arctic, especially those linking the atmosphere and cryosphere. We invite observational, modeling, and theoretical studies of the Arctic energy cycle, heat transport by atmospheric and oceanic circulations, and their relation to clouds, water vapor, cryosphere processes. This session is intended to provide a forum for reviewing our current understanding of Arctic energy balance and outline the challenges that lie ahead for advancing Arctic climate change prediction.
