Abstract: A theory of lee cyclogenesis is proposed, based on a linearized model of baroclinic wave generation by mountains in the presence of a background shear. The theory predicts that lee cyclogenesis will occur when the criterion for the existence of standing baroclinic lee waves is satisfied in the environment. For an infinite ridge, this requires that the component of wind across the ridge must reverse with height. The time scale for cyclone development, and the meaning of the ambiguous term ?lee? are clarified by examining the group velocity of the baroclinic waves. Time dependent three-dimensional solutions are discussed along with their application to Alpine Ice cyclogenesis.
