摘要:
利用1965—2020年广西91个国家气象观测站的逐日降水资料，对广西的台风与非台风暴雨过程时空变化特征进行统计分析。结果表明，台风暴雨和非台风暴雨时空特征差异明显。从时间变化看，两类暴雨过程发生频次的年际变化显著负相关，台风暴雨过程的平均综合强度、持续天数均大于非台风暴雨过程；两类暴雨过程发生频次的月际变化均呈单峰分布，非台风暴雨过程主要发生在4—8月，而台风暴雨主要在6—10月，期间其过程强度月平均值整体高于非台风暴雨过程。从空间变化看，台风暴雨过程降水中心集中在桂南和桂中部分地区，非台风暴雨过程降水覆盖广西大部地区；台风暴雨过程主要影响桂南沿海地区，各地受台风暴雨影响频率由桂南沿海向桂北地区逐级递减；非台风暴雨主要影响桂北地区，各地受影响频率在桂林、柳州、贺州、河池等市形成高值区。
Abstract:
Based on the daily precipitation data of 91 national meteorological stations in Guangxi from 1965 to 2020, the temporal and spatial variation characteristics of typhoon and non-typhoon rainstorm processes in Guangxi were statistically analyzed. The results show that the temporal and spatial characteristics of typhoon rainstorm and non-typhoon rainstorm are obviously different. From the perspective of time variation, the inter-annual occurrence frequency changes of the two types of rainstorm processes are significantly negatively correlated, and the average comprehensive intensity and duration of the typhoon rainstorm process are greater than those of the non-typhoon rainstorm process. The monthly occurrence frequency variation of the two types of rainstorms are in a single peak distribution. The non-typhoon rainstorm mainly occurs from April to August, while the typhoon rainstorm mainly occurs from June to October. The monthly average intensity of typhoon rainstorm process is higher than that of non-typhoon rainstorm process as a whole. From the perspective of spatial variation, the precipitation center of typhoon rainstorms are concentrated in southern and central Guangxi, and the precipitation of non-typhoon rainstorms cover most of Guangxi. The typhoon rainstorms mainly affect the coastal areas of southern Guangxi, and the frequency affected by typhoon rainstorm decreases gradually from the coastal areas of southern Guangxi to northern Guangxi. Non-typhoon rainstorms mainly affect northern Guangxi, and the affected frequencies are high in Guilin, Liuzhou, Hezhou, and Hechi.
