PS14B:
Turbulent Mixing of the Ocean Surface Boundary Layer: Observation, Simulation, and Parameterization V Posters

Session ID#: 92534

Session Description:
The turbulent ocean surface boundary layer (OSBL) communicates heat, mass, and momentum between the atmosphere and ocean interior, hosts the majority of oceanic primary productivity, and plays a key role in the evolution of the earth system over seasonal to centennial time scales. Representing variability in OSBL turbulent mixing is an abiding challenge in the modeling of earth systems due to the complexity of turbulent OSBL processes and their interaction with atmospheric turbulence, ocean interior mixing, surface waves, submesoscale processes, and sea ice.

This session invites contributions from both observational, numerical, and theoretical process studies as well as parameterization development work relating to OSBL turbulent mixing. We are interested in all processes that might affect OSBL turbulent mixing and the evolution of the OSBL, including wind-driven mixing, convection, and wave-driven turbulence --- as well as frontal instabilities and submesoscale baroclinic processes emerging from the breakdown of larger-scale currents.

The focus of this poster sub-session is on observation and parameterization of turbulent mixing in the OSBL.
