Atmosphere and Cryosphere Coupling in the Arctic: Observations, Modeling, and Implication for Future Arctic Changes
Session ID#: 71702
Session Description:
The Arctic is experiencing more rapid changes than anywhere else on Earth with far-reaching socioeconomic implications. Arctic climate variation in the last decade is a strong tell of the important yet delicate coupling between atmosphere and cryosphere in the region. The projected Arctic changes in response to rising CO2 by state-of-the-art earth system models still exhibit unacceptably wide spreads. These spreads partly stem from a lack of thorough process-level understandings of the energy budget in the Arctic, for both within the atmosphere and at the interface between atmosphere and surface. We invite observational and modeling studies of the Arctic energy cycle, its relation with clouds, water vapor, cryosphere processes, as well as heat transport by circulations. We hope this session will give the community a timely opportunity to review the current understandings and challenges ahead for advancing our knowledge about the Arctic energy cycle and climate change.
