摘要
利用国家站累积降水观测资料和NCEP/NCAR再分析资料对2018年8月滇西地区两次局地强降水过程进行对比分析,分别从大气环流背景、水汽条件、动力条件、不稳定条件等方面来探究两次降水成因的异同。
Based on the cumulative precipitation observation data and NCEP/NCAR reanalysis data of national stations, two local heavy precipitation processes in western Yunnan in August 2018 are compared and analyzed. The similarities and differences of the causes of the two precipitation are discussed from the aspects of atmospheric circulation background, water vapor condition, dynamic condition and unstable condition.
