中文摘要: 为探讨夏季不同大气环流背景下区域性暴雨过程副高结构特征及其对降水的贡献，利用2005
年6—7月降水量和NCEP/NCAR逐日再分析等资料，采用特征指数分析和物理量诊断方法，对
比分析了2005年夏季两次区域性暴雨的副高三维结构特征。结果发现，夏季不同的大气环流
背景下，两次区域性暴雨过程副高结构性质分别表现为热力性高压脊和动力性高压脊特征,
从而导致两次暴雨过程的水汽供应条件和产生强烈上升运动的大尺度背景场存在差异。
Abstract:Based on rainfall observation and daily NCEP/NCAR reanalysis dataset from June t
o July in 2005, a comparison of three dimension structures of subtropical high
for two regional heavy rainfall events is carried out with characteristic index
method and physical diagnosis analysis. The result shows that the subtropical hi
gh structure for the two events have different properties, i.e. thermal or dynam
ical. This has led to difference for these two events with respect to moisture t
ransport condition and large scale background for vertical motion.
