Abstract

The dispersing equation was derived from system of the hydrodynamic equations that take into account the gravity, and from boundary conditions of shock front. The dispersing equation made it possible to study unstable stability of front not only relative to sound vibrations, but also to explore the gravitational branch of acousto-gravitational waves. Within the framework of the model under study there appeared a possibility to examine the interval of frequencies in which wave disturbances of the aerosphere induced by shock waves from land-based sources are energized.
