摘要
受高空槽和副热带高压共同影响,2010年8月26～29日本溪地区出现暴雨、大暴雨天气过程。此次过程具有降水时间长、强度大、不断出现局地短历时强降水等特点,利用常规资料、卫星云图资料、雷达产品资料等对此次过程成因进行了分析,发现此次过程中副高位置的变化对预报降水起止时间、降水加强时间及降水落区的变化起了重要作用。
Because the combined effect of upper trough and subtropical high,rainstorm and downpour appeared in Benxi during August 26-28 of 2010,the process had the characteristics of long precipitation time,heavy intensity and short duration rainstorm and so on,the conventional meteorological data,satellite cloud images and radar products were used to analyze the cause of this process,the results show that the moving of subtropical high affected the starting time,strengthen time and drop zone of rainfall.
