摘要:
本文利用NCEP 1˚ × 1˚ (每隔六小时)FNL资料、TBB资料、以及台站的实况降水等资料，对2011年6月15日18时至16日00时的突发性暴雨过程进行了诊断分析。结果表明：此次突发性暴雨过程达到了高原上的标准暴雨强度，该降雨过程主要受北部冷空气及南部暖湿气流共同影响，且具有历时短、强度大等特征，水汽条件很充足；低层辐合高层辐散为暴雨的形成提供了相当有利的条件。
In this paper, NCEP 1˚ × 1˚ (every six hours) FNL data, TBB data, and station live precipitation data are diagnosed and analyzed the rainstorm during 15 June 2011 18:00 to 16 June 2011 00:00. The results show that: the rainstorm met the criteria storm intensity on the plateau, which is mainly affected by northern cold air and southern warm air, and the rainstorm has the characteristics of short duration, high intensity and the moisture conditions are adequate; low level convergence and upper level divergence are formed to provide a rainstorm quite favorable conditions.
