Abstract

Turbulence under strong stratification and rotation is usually characterized as quasi-two-dimensional turbulence. We develop a "quasi-two-dimensional" energy spectrum which changes smoothly between the Kolmogorov -5/3 law (no stratification), the -2 scalings of Zhou [Phys. Fluids 7, 2092 (1995)] for the case of strong rotation, as well as the -2 scalings for the case of strong rotation and stratification. For strongly stratified turbulence, the model may give the -2 scaling predicted by Herring [Meteorol. Atmos. Phys. 38, 106 1988], and the -5/3 scaling indicated by some mesoscale observations.
