Abstract: An analytical study of a strong point explosion in an inhomogeneous atmosphere proved that already at the early stage of development of this process, in a rather narrow spherical gas layer adjacent to a shock wave front from the inside, complex toroidal vortices form; these had been discovered earlier in a numerical experiment. Moreover, it was revealed that the source of this vortex generation was not scheme or pseudoviscosity but small perturbations of the shock wave front, initiated by weak (on the scale of the area of the explosion) atmospheric inhomogeneity at the initial stage.
