Abstract : The motion of frontal disturbances in the atmosphere is studied based on several nonlinear models proposed by Stoker. In the first model, the air is considered to be an incompressible fluid moving over a plane tangent to the rotating earth. The fluid consists of two layers and the density in each layer is assumed to be constant. The hydrostatic pressure law is then used to reduce this to a two space dimensional model. The boundary between these layers is a contact discontinuity and so instabilities may occur at this frontal surface. (Author)
