| 摘 要： | 利用完全弹性三维冰雹云模式,模拟研究了山东沾化2008年6月25日的一次冰雹过程,分析该地区冰雹形成的物理机制,在此基础上对雹云进行催化试验并研究催化防雹机制.结果表明,冰雹主要是以冻滴为核心增长的,催化使冻滴浓度增加,粒子质量减小,向雹转化的比例降低,致使冰雹的质量和浓度减小,从而达到防雹目的.

| Abstract: | A three-dimensional hailstorm numerical model with fully elastic primitive equations is used to simulate a hail cloud occurred in Zhanhua area,Shandong Province on June 25,2008.The mechanism of hail formation and hail suppression of this cumulus was analyzed.The results showed that most embryos of hail are frozen drops.The increasing of frozen drops concentration and decreasing of its average mass by seeding AgI caused the proportion of conversion from frozen drops into hail descend greatly and all these led the mass and concentration of hailstone to decrease to our purpose of hail suppression. |
