  Asymptotic properties of the solution of two-dimensional randomly forced
Navier-Stokes equation with long-range correlations of the driving force are
analyzed in the two-loop order of perturbation theory with the use of
renormalization group. Kolmogorov constant of the energy spectrum is calculated
for both the inverse energy cascade and the direct enstrophy cascade in the
second order of the $\epsilon$ expansion.
