Abstract: The structure of the most unstable baroclinic mode in the presence of elongated topography oriented parallel to the basic state zonal current has been investigated in a number of studies. The topographic modification leads ...

Abstract: Stationary solutions and their stability properties of nondissipative barctropic flow in a narrow, longitudinally periodic channel on a ?plane with a sheared basic current and bottom topography are investigated. An analytical ...

Abstract: This work is an extension of the normal mode theory of lee cyclogenesis in that it removes all the simplifications and restrictive assumptions contained in previous formulations Linearized primitive equations in isentropic ...

Abstract: Baroclinic instability in the presence of steep finite amplitude topography is studied in the primitive equation model. The quasi-geostrophic theory of Alpine cyclogenesis of Speranza et al. is reanalyzed and discussed in ...

Abstract: The presence of bottom topography in a baroclinic flow modifies the properties of the propagating baroclinic unstable modes and allows for the appearance of new unstable modes which are nonpropagating, as first shown by ...

Abstract: Observational and numerical studies on Alpine cyclogenesis have shown that a developing baroclinic wave approaching the mountain region gives rise to a disturbance of dipolar structure, extending throughout the troposphere ...
