It is extremely uncommon to be able to predict the velocity profile of aturbulent flow. In two-dimensional flows, atmosphere dynamics, and plasmaphysics, large scale coherent jets are created through inverse energy transfersfrom small scales to the largest scales of the flow. We prove that in thelimits of vanishing energy injection, vanishing friction, and small scaleforcing, the velocity profile of a jet obeys an equation independent of thedetails of the forcing. We find another general relation for the maximalcurvature of a jet and we give strong arguments to support the existence of anhydrodynamic instability at the point with minimal jet velocity. Those resultsare the first computations of Reynolds stresses and self consistent velocityprofiles from the turbulent dynamics, and the first consistent analytic theoryof zonal jets in barotropic turbulence.
