Linear disturbances induced by gravity-field inhomogeneities in a horizontal stratified flow with a vertical shear are calculated analytically. In addition to being dependent on the amplitude of these inhomogeneities, disturbances depend strongly on their horizontal scales, background flow velocity, stratification, and Coriolis parameter. The most important governing dimensionless parameters are the Froude number (the ratio of inertial forces and buoyancy) and the Burger number (the ratio of the effect of rotation to the effect of stratification). The analytical solutions derived show that the influence of inhomogeneities of the gravitational field on atmospheric flows can be significant in some cases. Physical generation mechanisms of these disturbances are analyzed.
