On the basis of the MGD equations we consider 2D- and 3D- nonstationary problems about the evolution of perturbations in the lower atmosphere and the Earth’s ionosphere which are caused by the movement of large meteoroids along gently sloping paths of the entry with the simulation of their destruction by the momentary increase of the midship at the point of the pressure head maximum. According to the results of our numerical investigation we obtain and analyze the detailed spatial-temporal distributions of the main parameters of the plasma flows from which in particular a number of phenomena that are similar to those seen in the Chelyabinsk phenomenon follow.

Keywords: the atmosphere, the ionosphere, numerical modeling, motion, and the destruction of meteoroids, the evolution of perturbations
