Non-universal features of forced 2D turbulence in the energy and enstrophy ranges. (English) Zbl 1115.76032
Summary: Analysis of energy spectra and fluxes of 2D forced incompressible turbulence in the energy range reveals marked departures from the \(-5/3\) law and the idea of spectral locality. Departures from the locality could also be diagnosed in the enstrophy interval, and in the energy range of beta-plane turbulence.
