Item Enstrophy dynamics of stochastically forced large-scale geophysical flows(2001-07) Blomker, Dirk; Duan, Jinqiao; Wanner, ThomasEnstrophy is an averaged measure of fluid vorticity. This quantity is particularly important in {\em rotating} geophysical flows. We investigate the dynamical evolution of enstrophy for large-scale quasi-geostrophic flows under random wind forcing. We obtain upper bounds on the enstrophy, as well as results establishing its Hölder continuity and describing the small-time asymptotics.
