Solutions are obtained for systems of equations that determine the development of velocity profiles in an infinitely deep fluid system subjected to Coriolis accelerations and composed of two layers of viscous fluid differing in density, viscosity, and geostrophic velocity. The density, viscosity, and horizontal pressure gradient are assumed to remain constant in space and time within each layer and to differ discontinuously at the horizontal interface between the layers....
