Navier--Stokes equation with random forcing.

ABSTRACT.  We use the balance relations for the stationary in time solutions of 
the randomly forced 2D Navier-Stokes equations, found by Kuksin-Penrose 
in \cite{KP05}, 
to study these solutions further. We show that the vorticity 
$\xi(t,x)$ of a stationary solution has a finite exponential moment, 
and that for any $a\in\R,\,t\ge0$ the expectation of the integral of 
$|\nabla_x\xi|$ over the level-set $\{x\mid\xi(t,x)=a\}$, up to a 
constant factor equals the expectation of the integral of 
$|\nabla_x\xi|^{-1}$ over the same set.
