PS001:
Deep Ocean Communication Through Topographic Pathways


Session ID#: 28760

Session Description:
Flows interact with topography in many ways, from creating internal waves and bottom boundary layers, to modifying the large-scale potential vorticity gradients and causing standing meanders.  Large-scale meanders and their associated storm tracks are mixing hot-spots for cross-front transport of heat and tracers and locations with larger vertical fluxes of momentum and energy, with implications for mixing and bottom drag.  Separately, understanding bottom boundary layers and dissipative process at topography has been improving with higher resolution modeling and observations.  These processes have been studied globally: in the Southern Ocean, western boundary currents, and other locations.  In this session, we aim to connect these two communities and highlight the interconnected dynamics of the eddy/mean flow-topography interaction and bottom boundary layer processes and bridge the gap between their two associated length scales to understand the role of topography in tracer and energy budgets.
