Abstract

The anisotropic characteristics of small-scale turbulence on the surface of a rotating sphere are described. Under strong rotation, a -5/3 slope prevails in other sectors far away from the zonal axis. This picture is consistent with the new flow regime. The concentration of energy in the zonal components and breaking of isotropy are caused by the anisotropic energy transfer. The capacity for the zonal jets to hold energy and remain stable increases with an increase of the meridional scale.
