Turbulent Air-Sea Fluxes: Observations and Modeling III


Session ID#: 36712

Session Description:
The physical coupling between atmosphere and ocean helps to drive a myriad of processes, such as surface material transport, air-sea gas flux, and wind-wave interactions. Fundamentally, the interfacial fluxes of energy and mass occur at the molecules-wide boundary between air and water. Outside of nominal open ocean conditions, the fine-scale nature of these dynamics poses a significant empirical challenge and numerically representing the air-sea coupling is not trivial. It is therefore necessary to come to a mechanistic understanding of the processes affecting exchange of mass and energy across the air-sea interface, and advances in both observational and numerical methods are needed. This session invites contributions to better consolidate the role of the ocean-atmosphere coupled system and is focused on expanding the current understanding of the mechanisms driving air-sea fluxes. Submissions on near-surface processes that can modulate the interfacial exchange are encouraged. Presentations of novel techniques, methods, and/or venues for air-sea interaction study are highly encouraged. The Chairs hope that this session facilitates a focused discussion on the physics of air-sea interaction, with input from an array of technical backgrounds and perspectives.
