Profile of Coherent Vortices in Two-Dimensional Turbulence

JETP Letters. 2015. Vol. 101. No. 3. P. 181-184.

The inverse cascade of two-dimensional turbulence in a restricted domain leads to creating a coherent flow containing a number of system-size vortices. We examine the case of forcing turbulence with zero bottom friction where the final statistically steady state is determined by viscosity. We analytically establish structure of the coherent vortices in the state.
