Numerical solution of the problem of explosion in planetary atmospheres in the Lagrangian variables

The problem of a low-power explosion in the terrestrial and Jovian atmospheres is considered in the Lagrangian variables. The distinctive features of the flow within the disturbed region encompassed by the blast wave are revealed in the numerical experiment. Apart from the singularity of the node type involved by the initial conditions of the problem, some other singular points arise in this region, namely, foci, saddles, and nodes. The effect of the relevant parameters on the flow pattern is determined.
