A31A:
Properties of the Ocean Surface that Directly Influence Air-Sea Exchange and Upper Ocean Dynamics I


Session ID#: 11367

Session Description:
The dynamical properties of the air-sea interface directly influence air-sea exchange of mass, momentum and energy. The presence of whitecaps, sea ice, oil spills, or surfactants will have a significant impact on the upper ocean dynamics, often in a complex interplay between the surface material, the mean flows in the air and water, and the surface waves. As far as ocean circulation models are concerned, such processes must be parameterized by changing the surface boundary conditions and/or modifying the internal model dynamics. One such example is the inclusion of sea state dependent momentum and energy fluxes, which is highly relevant for modeling the transport of dispersed oil or pelagic plankton.
 
In this session we welcome theoretical, numerical, and experimental studies of the properties of the air-sea interface. This includes how various surface covers impact on surface waves and also how the upper ocean currents and mixing depend on the waves and the properties of the air-sea interface itself.
