OS54A:
Measurement and Modeling of the Ocean Surface Boundary Layer II


Session ID#: 8210

Session Description:
The oceanic surface boundary layer is controlled by momentum and buoyancy fluxes near the surface and by entrainment fluxes at the base of the mixed layer. These fluxes generate a wide range of physical processes between the air-sea interface and thermocline, and play a vital role in climate variability, biological productivity, and marine pollution. The session encourages discussion of new techniques, field measurements and modeling of energy, momentum and heat fluxes near the air-sea interface, and within both ocean and atmospheric boundary layers. Studies of both field and laboratory observations, multi-scale modeling, and parameterizations of near-surface processes are encouraged. Topics of interest may include surface wave breaking, bubbles and air-gas transfer, and shear-, and wave-driven coherent structures, surface winds and heat fluxes, and rainfall impacts.
