Energy Transfers in Mesoscale and Submesoscale Turbulence: Towards energetically consistent theories and ocean models
Session ID#: 255115
Session Description:
This session explores energy transfer processes associated with mesoscale and submesoscale ocean dynamics. Mesoscale and submesoscale eddies play a critical role in the transport of heat and tracers, as well as in shaping ocean stratification.
Despite advances in computational capabilities, the parameterization of key energy transfers associated with these dynamics remains essential for global and regional ocean modeling.
For the development of accurate and physically consistent parameterizations, a thorough understanding of these energy pathways is fundamental.
We invite contributions that investigate energy transfers within the mesoscale and submesoscale turbulent regimes and their interactions with internal waves and small-scale mixing.
This includes studies based on numerical simulations, observational analyses, and theoretical approaches.
We particularly encourage submissions that assess the accuracy and consequences of energy transfer representations in current ocean models, whether through explicitly resolved processes or parameterizations, through spurious numerical effects, or through novel computational methods.
Contributions that propose or evaluate methods to improve the consistency and realism of energy transfers in future ocean model configurations by novel theories are also highly welcome.
We particularly encourage early-career researchers to participate in this session.
