| 摘 要： | 利用三维积云模式模拟2006年4月9日下午发生在广西东兰县境内的一次冰雹天气过程。结果表明,三维模式对该个例具有一定的模拟能力。个例催化数值试验表明,该积云具有一定的人工催化潜力,当在出现过冷水后,自然冰晶浓度较低前在过冷水区的底部实施适量的催化,则可达到最佳的效果,既能一定程度增雨又能一定程度消雹;当过量催化时则既能一定程度消雨又一定程度消雹。

| Abstract: | The hailstorm process in the northwest Guangxi is simulated with 3-D convective cloud model.The results show that the model is capable to simulate the case to some extent.A series of seeding experiments indicate that the cumulus cloud has some potential to be artificially modified.Effect can be optimized by proper seeding at the base of the super-cooled water area as natural crystal concentration is still at a low level.Seeding may somewhat cause the rainfall enhancement as well as the hail suppression.Meanwhile over seeding may lead to the rainfall decrease as well as the hail suppression. |
