A thin layer of ideal gas covering a rotating solid gravitating sphere is considered. The formulation of the problem implies to take into account inertial forces. The temperature of the sphere surface varies in latitudinal direction. It is assumed that all the unknown functions (density, temperature, pressure, velocities) are time-constant and do not depend on longitude. Then, if some limitation for a surface boundary condition is fulfilled a solution of the problem is 1D current that flows in latitudinal direction, i.e., perpendicular to the surface temperature gradient. The obtained solution possesses all the features of zonal winds that exist on many planets of the Solar System, including the possibility of super-rotation when the atmosphere moves faster than the planet's solid.
