On energy and enstrophy exchanges in two-dimensional non-divergent flow

  • Philip E. Merilees (a1) (a2) and Helen Warn (a3)
Abstract

It is shown that, in two-dimensional non-divergent flow in a bounded region, roughly 70% of triad interactions exchange more energy with longer wavelengths than with shorter wavelengths whilst roughly 40% exchange more enstrophy with longer wavelengths than with shorter wavelengths.
