2017年6月鲁西平原一次暴雨过程的特征分析

Characteristic Analysis of a Torrential Rain Process in Luxi Plains in June 2017

利用常规资料和NECP再分析资料对山东省聊城市2017年6月一次暴雨过程时间和空间分布特征进行分析。结果显示,该次暴雨过程由冷涡造成,不稳定能量较弱,造成了主要降水落区随时间变化明显,各站点降水时段又较为集中的特征。

Based on the conventional data and NECP reanalysis data, the temporal and spatial distribution characteristics of a torrential rain process during June 2017 in Liaocheng of Shandong Province were analyzed. The results showed that the torrential rain process was caused by the cold vortex and the unstable energy was weak, resulting in the characteristics of obvious changes over time in the main precipitation areas and the centralization of precipitation periods of the stations.
