Stochastic modeling of mesoscale eddies in barotropic wind-driven circulation

Résumé

We propose to follow a recent stochastic quasi-geostrophic model [4] derived from a decomposition of the flow into a resolved component and a time-uncorrelated uncertainty. One important characteristic of this random model is that it conserves the total energy along each realization. Such a stochastic principle has been tested for the numerical simulation of the wind-driven circulation in a shallow ocean basin. The numerical assement shows that the proposed random model can well capture on a coarse mesh the correct four-gyre time-averaged circulation structure, as predicted by a direct numerical simulation at a much finer resolution.
