Abstract: After the analysis of effective facts reported by scientists of China and USSR in the experiments of hail suppression, an obvious impression has been built. This point is that the explosive effect may play an important role except that of ice–crystallization by seeding. Therefore, the research of explosion effects on the meteorological phenomena has been emphasized in China and USSR. Some important results of this study can be enumerated as follows: The force effect on the airflow at the surrounding of explosion point which may damp the airflow at the speed of 3—4 m/s to zero. The lubrication effect on the motion regime of precipitation particle in the air which may lead on to the increase of fallspeed of hailembryo. There is a region whthin the hailcloud where the hailstone’s traveling trajectories of large hailstones in the growth processes appear to concentrate, and the relatively horizontal wind speed is equal to zero in the direction of hailcloud motion. From above, the technological gists of hail suppression by the method of explosion have been suggested briedfly
