Abstract
An initial stage of spontaneous generation of regular structures in st rongly turbulent rotating fluids is studied in the framework of the Ch arney-Hasegawa-Mima model [J. Pedlosky, Geophysical Fluid Dynamics (Sp ringer, New York, 1979); A. Hasegawa and K. Mima, Phys. Fluids 21, 87 (1978)]. it is shown that small-scale turbulence may maintain a regula r structure in a mean flow. The corresponding growth rate is shown to have a form of negative hyperviscosity. Possible applications in the t heoretical study of large scale vortices in the Jovian atmospheres are discussed.
