| Analysis of motion of the viscous temperature-stratified fluid with the presence of the rotation has been carried out on the basis of the linearized equation of motion in Boussinesc approximation. The diagrams in the space of wave numbers has been constructed to determine the motion type (gyroscopic, internal, gravity-gyroscopic waves and aperiodic motions) in dependence of the space scales of the perturbations and the medium parameters. It is shown that the boundary of the aperiodic zone has characteristic "rostral" shape, exact relationship determinig the position of the angular point is found. The corresponding asymptotic solutions describing the wave and aoeriodic regimes of motion have been found for these zones. The diagram of motion in the "f-plane" approximation has been constructed too. The comparison of this diagram with the diagram constructed without this approximation is fulfilled. |
