The effects of inclusion of vertical shear in the problem of steady flow of an inviscid, rotating and stratified fluid past isolated topography are discussed. It is shown that the presence of baroclinicity in the undisturbed flow far from the obstacle, in the parameter range considered here, produces an anti-cyclonic vortex bound to the obstacle, like in the unsheared case, but whose intensity is modified by the shear. In particular, if the velocity of basic flow increases with height, the intensity of the vortex is decreased with respect to the barotropic case, because of the horizontal advection of potential temperature. Analytical solutions are presented in the case of small amplitude obstacles. |
