Abstract : A similarity solution for the first order perturbation of a nearly spherical strong blast wave generated by a point source in a mildly stratified medium is found. The hydrodynamic equations include a radiation diffusion approximation to radiation transport which is of such a character to allow both the unperturbed and perturbed solutions to exhibit a similarity form. The cylindrically symmetric solution provides the flow in both radial and polar directions. Implications for circulation in flow fields of low-altitude atmospheric explosions are drawn.
