Abstract
A spectral closure analysis and numerical simulations suggest that there ma y be a class of two-dimensional turbulence in which the energy spectrum E(k ) scales with the wave number k like E(k)=Ak(-3) in the enstrophy transfer range in accordance with the Kraichnan-Leith-Batchelor (KLB) spectrum, but the prefactor A is different from the KLB spectrum and depends in a nontriv ial way on the flow conditions at large scales.
