2016年7月22～23日新津机场大暴雨成因分析
|
摘要
本文利用常规实测资料、NCEP/NCAR再分析资料,对新津机场2016年7月22~23日出现的一次大暴雨天气过程进行环流场和物理量的分析,结果表明:此次强降水主要发生在22日傍晚至23日凌晨,在高空低压槽、副热带高压、西南低空急流以及冷空气活动的共同作用下发生的,降水过程的动力、热力及水汽物理量场的分析结果反应出各系统之间的相互配合,大暴雨的降水量与各物理量场的结果相对应。
Based on the conventional observation data and the NCEP/NCAR reanalysis data, the circulation and physical quantity fields of a heavy rainfall in the Xinjin Airport during July 22-23, 2016 are analyzed. The results show that under the effect of the upper trough, the subtropical high, the southwesterly low level jet and the weak cold air, the heavy rain occurred mainly during the evening of the 22 th to the early morning of the 23 th. The analysis results of the dynamic, thermodynamic and physical quantity fields of the process reflect the coordination among the systems. The intensity of the heavy rain corresponds to the results of the physical fields.
