The propagation of blast waves is strongly influenced by atmospheric conditions. The effect of non-uniform temperature distribution on the blast wave propagation in the atmosphere is investigated at the Shock Wave Research Center (SWRC), Institute of Fluid Science, Tohoku Univ. The temperature difference of five degrees in the vertical direction is created in the 1000 mm x 700 mm explosion box, in which the spherical blast waves are generated by igniting 10 mg of AgN₃ pellet. The propagations of blast waves are successfully observed and visualized by using double exposure holographic interferometory.
