Anisotropic turbulence and zonal jets in rotating flows with a β-effect

Abstract:

Numerical studies of small-scale forced, two-dimensional turbulent flows on the surface of a rotating sphere have revealed strong large-scale anisotropization that culminates in the emergence of quasi-steady sets of alternating zonal jets, or zonation. The kinetic energy spectrum of such flows also becomes strongly anisotropic. For the zonal modes, a steep spectral distribution, E(n)=Cz(Ω/R)^2 n^-5, is established, where Cz=0(1) is a non-dimensional coefficient, Ω is the angular velocity, and...
