Polar air-sea interactions in a warming climate
Session ID#: 259704
Session Description:
Air-sea fluxes of heat, momentum, carbon, and other gases in the polar regions play a key role in global climate. For example, the decline in sea ice reduces surface albedo and modifies atmospheric circulation, influencing surface temperatures, precipitation, and weather both locally and globally. These changes are opening new Arctic shipping routes, such as the Northwest Passage and the Northern Sea Route, significantly shortening travel distances between Asia to Europe and Asia to eastern North America. Meanwhile, in the Southern Ocean, growing evidence suggests that synoptic- and fine- scale air-sea interactions also influence the larger scale mixed-layer budgets of heat, carbon and other tracers. However, the mechanisms of multi-scale interaction and energy exchange remain poorly understood
and quantified.
Within this frame, this session seeks to cover the full spectrum of air-sea fluxes and feedbacks, from microscale turbulence to large-scale climate mode, including wave-ice interactions and decadal variability. We welcome contributions focused on the Arctic and/or Antarctic, as well as studies utilizing in situ observations, satellite data, and numerical models. Understanding polar air-sea interactions in a warming climate is essential for advancing climate science and responding to emerging economic opportunities.
