中文摘要：

在暴风雨降雨的时间的变化在这研究在在华南(SC ) 的第一雨季(皇家学会会员) 期间被调查。结果证明在暴风雨降雨的内部年度的变化在在 SC 的 FRS 期间似乎被暴风雨降雨的频率主要影响，当频率和紧张在全部的暴风雨降雨影响内部十的变化时。为 FRS，和发作的开始并且结束的日期使用定义在 SC 夏天季风标明日期， FRS 进一步被划分成二亚时期，即，正面并且季风降雨时期。在暴风雨降雨的内部年度、内部十的变化这里在这二个时期期间被调查。结果揭示重要 out-of-phase 关联在之间正面并且季风暴风雨降雨特别在内部十的 timescale 上，为哪个要求进一步的调查的物理机制。

英文摘要：

The temporal variations in storm rainfall during the first rainy season （FRS） in South China （SC） are investigated in this study. The results show that the inter-annual variations in storm rainfall during the FRS in SC seem to be mainly influenced by the frequency of storm rainfall, while both frequency and intensity affect the inter-decadal variations in the total storm rainfall. Using the definitions for the beginning and ending dates of the FRS, and the onset dates of the summer monsoon in SC, the FRS is further divided into two sub-periods, i.e., the frontal and monsoon rainfall periods. The inter-annual and inter-decadal variations in storm rainfall during these two periods are investigated here. The results reveal a significant out-of-phase correlation between the frontal and monsoon storm rainfall, especially on the in- ter-decadal timescale, the physical mechanism for which requires further investigation.
