摘　　要：本文对广州市24小时降水的分布特征进行了统计分析。结果表明:广州全年出现降水的概率为39％,汛期出现降水的概率远大于非汛期,其中6月份出现降水的概率最大,而10～12月份的概率则最小;前、后汛期与全年平均强降水频数的24小时分布相一致,其中极大值在上半夜,极小值在早晨,而非汛期则是白天大于夜间。Statistical analyses are carried out on characteristics of 24 hour rainfall distribution in Guangzhou. The result shows that the probability of precipitation occurrences in Guangzhou is 39% for a year, and much higher in the rainy season than the other, with maximum in June and minimum in October-December. The 24 hour distribution of mean heavy rainfall frequency is consistent among the early rainy season, late rainy season and the whole year, with maximum rainfall in early night and the minimum in late night, and otherwise in the non-rainy season.
