Two-dimensional self-similar gas-dynamical flow generated by the explosion of a meteor body in the atmosphere.

The explosion of a meteoroid in the atmosphere is investigated on the basis of the classical model of a powerful point explosion in an ideal gas (see Sedov, 1987). Particular emphasis is placed on the extent to which the dynamics of the process is affected by the gasdynamic wake of the meteoroid arising during its motion in the atmospheric prior to the explosion. It is demonstrated that the resulting flow has a self-similar character.
