Abstract

Hail suppression by the explosion method has been used for many years in China. Generally the small gun, small rocket, and anti-aircraft gun are used as delivery systems. According to the analysis of data in some counties of China (1, 2) hail suppression by the explosion method has obtained some successes in the reduction of hail damage. However, the question of the actual influence of explosions on hail clouds still remains unknown. Vittori (3) noticed the mechanical effect of shock wave on hailstones (mechanism of cavitation). Goyer (4) had demonstrated that the mechanical effect of weak shock waves can induce freezing in supercooled water. However, the experience of hail suppression in China indicated that the explosion can rapidly induce the formation of such phenomena as precipitation, hole in the cloud, weakness of cloud intensity, etc. (5, 6, and 7). These phenomena cannot be explained by the above mentioned mechanism. Since 1972 a series of simulated and field experiments have been conducted for purposes of clarifying the physical influence factors of explosions on the development of convective clouds.
