Abstract
We use numerical simulations to prove that the dynamics of the small-scale vorticity in two-dimensional incompressible fluids is nearly passive and that the feedback of the small scales onto the large-scale dynamics is important only for the part of the large-scale range which is adjacent or close to the small-scale range.Keywords
