Abstract
The logarithmic renormalization predicted by Kraichnan (1971) for the direct cascade of enstrophy in the incrtial range of two-dimensional turbulence has been observed in a numerical simulation. A moderate resolution allows for a very long time integration that provides very good statistics. Deviations from Gaussianity in the vorticity probability distribution arc observed. © 2002 The American Physical Society.
