Analysis of Motion of a Viscous Stratified Fluid at Presence of Rotation
RÉSUMÉ
Analysis of motion of the viscous temperature-stratified fluid at presence of rotation has been carried out on the basis of the linearized equation of motion in the Boussinesq 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 on 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 determining the position of the angular point is found. The corresponding asymptotic solutions describing the wave and aperiodic 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.
