Abstract

This paper reviews some recent results concerning the formation and structure of zonal jets in forced shallow water turbulence on the surface of a rotating sphere. Attention is given to the role of the Rossby deformation radius in determining the degree to which jets align zonally; to the limiting case of the axisymmetric "potential vorticity staircase"; and to the issue of equatorial superrotation, which is shown to arise robustly when energy is dissipated through a representation of radiative relaxation.
