Abstract: Baroclinic instability in the presence of a meridionally sheared barotropic component to the basic flow is studied using a two-level model. The inclusion of a linear shear results in merldionally confined normal modes with ...

Abstract: The existence of boundary baroclinic instability (as exemplified by the Eady or Charney problems) and internal baroclinic instability, which requires the potential vorticity gradient to take both signs in the fluid interior, ...

Abstract: Lifecycles of baroclinic waves obtained by integrating the primitive and quasi-geostrophic equations on the sphere are compared. Two basic states are considered. The first is based on Northern Hemisphere winter climatology, ...
