Non‐Local Eddy‐Mean Kinetic Energy Transfers in Submesoscale‐Permitting Ensemble Simulations
Résumé
Meso-scale eddies play a crucial role for the energetic balance of the ocean, providing the main pathway toward dissipative scales (Wunsch & Ferrari, 2004). Understanding how eddies interact with the mean flow thus helps our interpretation of the ocean circulation, and also serves as a basis for the development of robust parameterizations for ocean models. In order to gain insights from the different processes controlling eddy energetics, it is usual and natural to investigate the different terms contributing to the time rate of change of the Eddy Kinetic Energy (EKE) equation (e.g., Dewar & Bane, 1989; Webster, 1961, 1965). From the point of view of parameterization, evaluating the energy levels of meso-scale "eddies" is used to constrain numerical eddy dissipation
