The 2D enstrophy cascade was proposed independently of Kraichnan, and even somewhat earlier, by Batchelor.
This led Bray to suggest an enstrophy cascade with a k-1 spectrum and thus a k-3 energy spectrum.
Kraichnan also studied the 2D enstrophy cascade and, in particular, worked out the log- arithmic correction mentioned in 1967.
A number of numerical studies of the enstrophy cascade with 'hyperviscosity' (powers of the Laplacian replacing the usual dissipative term) have reported observing the log-correction to the energy spectrum.
However, several recent observational studies have found evidence for both inverse energy and direct enstrophy cascades in the Earth's atmosphere and oceans.40
