Краткое описание

The propagation of acoustic-gravity waves (AGW) in a rotating medium was investigated. In a simple model it has been shown that the AGW frequencies, close to the Brunt−Vaisala frequency, may occur in the presence of vortex motion of the medium. These waves propagate against the direction of rotation of the medium and have a horizontal scale of hundreds of kilometers. The obtained results enable one to explain the AGW main observed features in the polar thermosphere by the presence of background large-scale vortex motions.
