The Boussinesq model of convection in a flat layer with heating from below is considered. We analyze the effects of anisotropy caused by rapid rotation in physical and wave spaces and demonstrate the suppression of energy transfer by rotation.Wealso examine the structure of thewavetriangle in nonlinear interaction. The range of parameters is adapted to the models of convection in the geodynamo.
