当前外场防雹试验的若干情况

本文主要根据最近几次国际人工影响天气会议文集及有关资料,介绍了苏联、美国、中国以及许多欧洲国家的外场防雹试验情况、防雹作业方法与效果评估方法,特别是冰雹落地动能统计法。 对于防雹作业来说,取得成功的关键是及时、准确地确定播撒部位和作业时机。

The current status of hail suppression experiment in the field

The recent status of hail suppression in Soviet Union, United States, China, and many countries in Europe are presented, based on the results published in the international weather modification conferences. The methods of hail,suppression operation and evaluation of hail prevention effects, especially the statistical method of kinetic energy of hail fall to the ground are also involved in the paper.Timing and correct placement of seeding materical and time of seeding are particularly critical to "successful suppression.
