Energy Pathways and Parameterization in Global Ocean Models - Internal Waves and Submesoscale Dispersion
Session ID#: 258451
Session Description:
Recent advances in ocean global circulation models (OGCMs) have enabled the partial resolution of low-mode internal waves and the transition from parameterizing to explicitly resolving mesoscale features. These developments open new opportunities to investigate how energy is transferred across scales and how these pathways affect submesoscale lateral dispersion. A key area of interest is the interaction between internal waves and geostrophic flow, including how wave–vortex coupling influences energy redistribution, mixing, and tracer transport. This session focuses on the challenges and opportunities in characterizing and parameterizing energy transfer mechanisms, particularly in relation to submesoscale variability and dispersion processes. We welcome contributions that bridge gaps between different modeling communities, and that encourage discussion on how internal wave-driven energy pathways intersect with geostrophic and submesoscale dynamics to shape the structure and predictability of ocean circulation. Contributions that emphasize methodological innovations, including diagnostics, model-data comparisons, and scale-aware parameterizations are particularly welcome. We also invite observational, theoretical, and numerical studies that advance the representation of these processes in OGCMs and enhance their relevance for climate-scale simulations.
