PS53A:
How Do Submesoscale and Internal Wave Driven Mixing Matter on Global and Regional Scales? III


Session ID#: 36946

Session Description:
Ocean mixing processes driven by submesoscale dynamics (e.g. mixed layer instabilities, shear instability, etc), internal waves (e.g. nonlinear wave interactions, lee waves, etc), and the interaction between the two are known to have a significant local impact. However, less is known about the importance of these mechanisms on larger scales, including the effect on the water-mass transformation, buoyancy budgets, energy pathways, and subsequent biogeochemistry. This is due to the challenges of observing and modeling these processes accurately with regional and global coverage. This session welcomes abstracts that help investigate the influence of these small-scale processes (occurring at time scales of inertial periods and spatial scales below 10km) on the large-scale by use of observations, modeling, or parameterizations. We hope to initiate discussions that relate to the regional, basin, and global scale effects of submesoscales and internal waves on the physics and biogeochemistry of the ocean.
