HE11A:
High Latitude Air-Sea-Ice Interactions  in a Changing Climate I


Session ID#: 11361

Session Description:
Exchanges of heat, mass and momentum across the air-sea interface impact the ocean and atmosphere and their interactions within the coupled climate system.  These exchanges, significantly enhanced in polar regions by large air-sea temperature differences and high wind speeds, contribute to water mass modification and ventilation that in turn impacts biochemical and physical conditions throughout the world oceans. Sea ice modulates these processes and results in complexity that, combined with a sparsity of data in polar regions, contributes to uncertainty regarding their spatial and temporal variability and large scale impacts.  This session provides a venue for the exchange of new information on all aspects of high latitude air-sea-ice interaction, including processes at the interface and investigations of their impacts on local ocean, atmosphere, and sea ice processes as well as the larger coupled climate system.
