摘要
2009年4月28～29日北疆出现了大到暴雨天气过程,暴雨区位于乌鲁木齐—木垒。高空深厚低槽的东移、槽底西北风和西南风的强切变造成该暴雨天气。西、南2路水汽加厚了暴雨区水气的聚集厚度。高空急流激发的次级环流加强了暴雨区的上升运动和地面天气系统。
A heavy-hard rain weather process appeared in north Xinjiang in 28 - 29 of April in 2009. The heavy rain area appeared from Urumehi to Mulei. The weather process was caused by east movement of deep low trough in high altitude and strong shear of northwest and southwest wind at trough bottom. The aggregation thickness of the vapor in heavy rain area was thickened by west and south vapor. The ascending motion and surface weather systems in heavy rain area were strengthened by secondary circulation that excited by upper level jet.
