Dispersion of passive tracers in model flows: effects of the parametrization of small-scale processes

A set of numerical experiments is presented, in which we study the dynamics of passive particles advected by given two-dimensional velocity fields and perturbed by a non-white noise with a characteristic time τ. Data and model results have shown that this kind of random perturbation i...
