Parameterization of submesoscale eddy-rich flows using a stochastic velocity model

Abstract

In light of the recent high-resolution radar data of surface velocity, which have revealed submesoscale eddies between the Florida Current and the coast, an objective method of detecting eddies and estimating their parameters such as center coordinates, size, and intensity is suggested. The obtained statistics are used to parametrically represent the birth-death process of eddies filling up the observation area via a model stochastic velocity field known as Cinlar flow. It appears that the suggested approach leads to a reasonable parameterization of this process for potential future use in OGCMs or coastal models.
