On disturbances of the geostrophic flow influenced by volume sources of buoyancy and momentum

As is well known, flows in a free atmosphere outside a narrow equatorial zone are characterized by a geostrophic regime. For several applications, it is of interest to estimate the disturbances of the geostrophic wind caused by the action of sources of heat and/or momentum. One possible example is associated with manifestations of internal gravitational waves. A linear analytical model of the geostrophic flow disturbances of a stratified rotating medium caused by the action of stationary sources of momentum and/or buoyancy is considered. The model makes it possible to estimate explicitly the amplitudes of such disturbances depending on the parameters of the sources and the characteristics of the medium.
