Abstract: The study of the stability of two-layer baroclinic flows in a zonal magnetic field (Part II) is generalized to include a parabolic flow profile in the upper layer. Contrary to the nonmagnetic case, angularities may be ...

Abstract: Because of its possible applications to the solar differential rotation, hydromagnetic dynamo theory, and the geomagnetic secular variation, the dynamics of baroclinic, geostrophic ?-plane flow in a zonal (toroidal), ...

Abstract: The properties of quasi-geostrophic, baroclinic flow in a zonal magnetic field, as formulated previously by the writer, are examined for a zonal flow profile of hyperbolic tangent form in the vertical coordinate. The ...

Abstract: The equations of Part I are approximated to represent a two-layer model. All the theorems for the continuous case are shown to hold in the two-layer case as well. In addition, bounds are placed on the phase velocities of ...

Abstract: We present extensive linear numerical simulations of Boussinesq convection in a rotating spherical shell of finite depth. The motivation for the study is the problem of general circulation of the solar convection zone. We ...
