The Ocean Surface Boundary Layer: Physical Processes and Roles in Weather, Climate, and Biogeochemistry II Posters
Session ID#: 9952
Session Description:
The ocean surface boundary layer (OSBL) lies at the interface between the atmosphere and the ocean. It mediates energy and mass exchange between the two, with significant ramifications for a variety of climate, weather and biogeochemical phenomena.
Observations of upper ocean properties remain sparse and numerical models are limited by computational restrictions, incomplete representation of fine-scale turbulent processes, and boundary condition errors. Capturing OSBL variability on a global scale remains a critical challenge that requires the development of new approaches to observation, estimation and modeling. Recently, the OSBL has been the subject of intense theoretical study and turbulence resolving modeling, demonstrating, for example, that surface waves and sub-mesoscale processes play key roles in OSBL deepening and shoaling. These developments have motivated new in situ observational programs that are just beginning to report results. The combination of this new theory, large eddy modeling and observations has the potential to drive a new generation of OSBL parameterizations for numerical models and inform requirements for a global OSBL observing system. Abstracts that discuss theoretical, modeling, parameterization or observational studies of the OSBL, or work illustrating OSBL impacts on weather/climate or biogeochemical phenomena are all within scope.
