Abstract: Baroclinic modon solutions of the two-level quasigeostrophic vorticity equations on a sphere are presented. These modons with both barotropic and baroclinic components can be made stationary in a zonal background with ...

Abstract: The linear stability of two stationary dipolar modon solutions of the nondivergent barotropic vorticity equation on a rotating sphere is investigated. A numerical normal mode analysis of the linearized equation is performed ...
