Linear transformation of Rossby waves in shear flows
Chagelishvili G. D. , Chkhetiani O. G.
The dynamics of a shallow, nonuniformly rotating atmosphere in the presence of a zonal shear flow is studied. A new effective mechanism, which is ignored in the standard quasigeostrophic approximation that leads to the Charney-Obukhov equation, is demonstrated for the transformation of Rossby waves into inertial waves. The discovery of this phenomenon was made possible by the application of the currently highly popular nonmodal analysis, in hydrodynamics, of the evolution of disturbances in hydrodynamic shear flows. © 1995 American Institute of Physics.
