Intermittency in two-dimensional Ekman-Navier-Stokes turbulence

Abstract

We study the statistics of the vorticity field in two-dimensional Navier-Stokes turbulence with a linear Ekman friction. We show that the small-scale vorticity fluctuations are intermittent and that their statistics coincides with the one of a passive scalar with finite lifetime transported by the velocity field itself.
