Steady radiating baroclinic vortices in vertically sheared flows

Surface Waves on Vertically Sheared Flows: Approximate Dispersion Relations

Assuming linear wave theory for [1974] for deep water. We then obtain solutions waves riding on a weak current of O(c) compared to to the general problem to 0(1⁄2) (reproducing the the wave phase speed, an approximate dispersion result of Skop [1987]) and to 0(1⁄22). In section 3 relation is developed to 0(1⁄2 2 ) for arbitrary curwe apply the method to linear, cosine, and 1/7rent U(z) in water...

Physical Simulation of Baroclinic Waves and Vortices in the Atmosphere

Baroclinic Vortices over a Sloping Bottom

Nonlinear quasigeostrophic flows in two layers over a topographic slope are considered. Scaling the lower layer potential vorticity equation yields two parameters which indicate the degree of nonlinearity in the lower layer. The first, u' (the strength of the deep flow divided by the product of the effective bottom slope and the squared length scale), is related to the advection of relative vor...

Numerical Simulation of Baroclinic Jovian Vortices

We examine the evolution of baroclinic vortices in a time-dependent, nonlinear numerical model of a Jovian atmosphere. The model uses a normal-mode expansion in the vertical, using the barotropic and first two baroclinic modes. Results for the stability of baroclinic vortices on an f plane in the absence of a mean zonal flow are similar to results of Earth vortex models, although the presence o...
