PS34B:
Interactions Between Internal Waves and Mesoscale/Submesoscale Currents: Physics and Impacts on Ocean Energetics and Mixing III Posters

Session ID#: 85089

Session Description:
Mesoscale eddies and low-frequency internal waves contain most of the ocean kinetic energy. It has been speculated that energy transfers between the waves and eddies play a leading-order role in their respective kinetic-energy budgets. Theory and analysis of numerical models suggest that these energy transfers are facilitated by features in the flow associated with strong vorticity, strain, and lateral density gradients, but our understanding of the relevant physics and our observations of these transfers in action are still emerging. Interactions between waves and both mesoscale and submesoscale currents can also impact internal wave-driven mixing by locally enhancing wave shear and turbulence. Our nascent understanding of the physics and impacts of these interactions warrants closer examination. This session invites contributions from observational, numerical, and theoretical studies on the physics of the interactions between internal waves and mesoscale/submesoscale currents and their impacts on regional to global scales.
