The flow and condensation of supersonic steam jet submerged in the quiescent subcooled water were investigated experimentally at first. 首次针对超音速蒸汽在过冷水中浸没射流流动与凝结换热特性进行了系统的实验研究。
AgI-seeding should be done before the activation of most ice nuclei start, so as to enhance rainfall through increasing ice crystals content, and deleting super-cooled cloud water. 结果表明，该地区秋季对流云降水主要为冷云降水，冰晶是霰产生的主要来源，冰霰自动转化是霰产生的最主要方式，冰晶与霰的碰并又促进了霰的进一步增长，霰是云中过冷水消耗的主要因素。
