摘    要:在三维冰雹云模式基础上,采用湿热泡扰动方式激发对流云,对1998年7月21日发生在河南北部地区的一次冰雹过程进行模拟并做催化试验.结果表明,该例雹云具有含水量累积区,对累积区中心播撒碘化银能够减雹、增雨;而在此中心之下较低的高度作业,或播撒时间选取不当,则有可能增加冰雹.

关 键 词:雹云模式    数值试验    人工防雹.

Abstract:On the basis of the theory of liquid water accumulation for hail-formation and growth, some numerical experiments have been done to study effects of AgI seeding by using 3D hail cloud model. The data used here was taken from the profile of a hailstorm occurred in Henan Province on July 21,1998.Through these experiments, we found that the seeding time and height were very important to effects. If the seeding time is not right, maybe the hail accumulation on ground will be increased. However, increasing hail will be occurred if seeding height is not reasonable even if the time is right. Generally, initial seeding in the accumulation core will lead to hail suppression, but below this level, maybe enable hail accumulation on ground to increase.
Keywords:hail cloud model  numerical experiment  hail suppression
