Quasinormal scale elimination theory of the anisotropic energy spectra of atmospheric and oceanic turbulence
Boris Galperin, Semion Sukoriansky
Abstract
Quasinormal scale elimination theory of rotating turbulence offers a new explanation of physics governing atmospheric and oceanic spectra including the well-known Nastrom and Gage spectra observed in the upper troposphere and lower stratosphere. The terrestrial circulations may be characterized as flows with ``compactified dimensionality'' (spatial dimension between 2 and 3). Such flows may have both inverse and direct cascades in the same inertial range (dual cascade) and their spectral amplitudes may be determined not by energy/enstrophy fluxes, but by the magnitude of the Coriolis parameter.
