摘要
利用WRF3.7.1模式和0.75°×0.75°ECMWF再分析资料,对2018年6月10日宁夏六盘山区发生的一次降雹过程进行了模拟。结果表明,此次生命史长达3 h的多单体冰雹云具有不断生消的发展特征。水汽充足的地方易形成各类水成物粒子,冰核核化形成冰晶,冰晶碰并形成雪晶,后与过冷雨滴冻结产生霰,霰增长、转化,形成冰雹。
Based on the ECMWF reanalysis date with 0.75° ×0.75° spatial resolution, the strong convective weather in Liupanshan Area of Ningxia on June 10,2018 was simulated by Weather Research and Forecasting(WRF) model. The results show that the multi-monomer hail cloud with a life history of up to 3 hours has the characteristics of continuous generation and extinction. In places with sufficient water vapor, it is easy to form various hydrometeors. Ice crystals are formed by ice nucleation, which collide with each other to form snow crystals, and then freeze with supercooled raindrops to produce graupel,which grows and transforms to form hail.
