Lately, the problems of propagation of acoustic-gravity waves in the atmosphere
and of influence of these waves on the atmosphere call significant interest. It
is, for example, the problems of generation of waves by an auroral electrojet. These are also the problems of generation of waves by diverse meteorological phenomena and of influence of these waves on the upper atmosphere and ionosphere. These are the problems of origin and evolution of tornadoes and the problems of waves generated by tornadoes. These are the problems of atmospheric convection, storms and squalls and of influence of these phenomena on the upper atmosphere. These are also the problems of wave propagation from earthquakes, or of wave propagation from micro-oscillations of the Earth surface before earthquakes. For modeling and examination of these diverse phenomena, the authors in the beginning of 2000’s have developed a supercomputer numerical model based on numerical integration of non-linear complete three-dimensional system of hydrodynamic equations.
