    "abstract": "We explain the emergence and robustness of intense jets in highly turbulent\nplanetary atmospheres, like on Jupiter, by a general approach of statistical\nmechanics of potential vorticity patches. The idea is that potential vorticity\nmixing leads to the formation of a steady organized coarse grained flow,\ncorresponding to the statistical equilibrium state. Our starting point is the\nquasi-geostrophic 1-1/2 layer model, and we consider the relevant limit of a\nsmall Rossby radius of deformation. Then narrow jets are obtained, scaling like\nthe Rossby radius of deformation. These jets can be either zonal, or closed\ninto a ring bounding a vortex. Taking into account the effect of the beta\neffect and a sublayer deep shear flow, we predict an organization of the\nturbulent atmospheric layer into an oval-shaped vortex amidst a background\nshear. Such an isolated vortex is centered over an extremum of the equivalent\ntopography (determined by the deep shear flow and beta-effect). This prediction\nis in agreement with analysis of wind data in major Jovian vortices (Great Red\nSpot and Oval BC).",
