| 摘 要： | 为解阳江夏季降水的气候特征，进一步做好阳江气候降水预测，利用Motlet小波分析理论、Mann-Kendal检验和滑动t检验等方法对阳江单站57年（1953—2009年）6月到8月逐日降水资料进行分析，结果表明：阳江夏季降水经历了3个阶段，由降水逐渐增加时期变化到相对干旱时期，再到现阶段降水年际变化大；主要的降水周期为7—8年，1963年是降水的突变点；小雨量级降水为主要降水类型，在1980年以来阳江夏季大雨和暴雨降水日数逐渐增多，而大雨和暴雨量级降水是降水量的主要构成。

| Abstract: | The purpose of this paper is to realize the climate characteristics of Yangjiang summer precipitation and to do a better job in the climate forecast of Yangjiang summer precipitation. This paper analysizes daily summer precipitation data of Yangjiang from 1953 to 2009 by using Motlet wavelet analysis, M-K test and MTT. The results show, the summer precipitation of Yangjiang has gone through three stages, now in the stage has big interannual change. The summer precipitation has a period of 7 to 8 a, and abrupt changes occurred in 1963. The main precipitation type is light rain. After 1980, the rainfall days of heavy rain and rainstorm are increasing. The main components of precipitation are heavy rains and rainstorm. |
