AI31A:
Fluxes and Physical Processes Near the Air-Sea Interface: Observations and Modeling (Cosponsored by the AMS Committee on Air-Sea Interaction) I

Session ID#: 93391

Session Description:
The physical coupling between atmosphere and ocean helps to drive a myriad of processes such as wind-wave growth and the fluxes of momentum, heat, and mass across the air-sea interface. Challenges remain in understanding the nature of the air-sea interface in extreme conditions and along coastal margins, as well as characterizing the link between large- and small-scale processes.  Understanding these phenomena hinges on properly characterizing the physical coupling between air and water across the surface and the turbulent variability in the boundary layers on both sides of the interface. Advances in the spatial and temporal resolution and coverage of in situ observations, modeling, and satellite/airborne remote sensing have greatly improved the ability to characterize various surface processes over large stretches of oceanic area. This session invites contributions that expand our understanding of the mechanisms coupling the ocean-atmosphere system; submissions from observations, experiments, and/or modeling are encouraged. Presentations of novel techniques, methods, and/or venues for air-sea interaction study are highly encouraged. The Chairs hope that this session provides a forum for discussions on the physics of air-sea interaction, with input from an array of technical backgrounds and perspectives. This session is co-sponsored by the American Meteorological Society’s Committee on Air-Sea Interaction.
