It is prone to extreme precipitation in Guangdong Province. In this paper, the hourly precipitation of 1 553 days of 3 370 sites from January 1 in 2013 to March 16 in 2017 are selected. Using statistical method, hot spot analysis and pan Kriging method,the main characteristics of temporal and spatial distribution of extreme precipitation are analyzed in Guangdong Province. The results show that the extreme precipitation is mainly concentrated from April to October, accounting for about 78% of the annual precipitation. The spatial distribution of extreme precipitation and extreme precipitation events in Guangdong is basically the same. From different regions,the spatial distribution of extreme precipitation in Guangdong Province is uneven. The total number of extreme precipitation events in Shanwei-Shantou-Jieyang,Yangjiang in westun Guangdong-Maoming, Shaoguan in northern Guangdong and Jiangmen-Huizhou in the pearl river delta reaches 57 756, accounting for 71%. The total number of extreme precipitation events in Shaoguan-Qingyuan north,Meizhou west-Heyuan north,Yunfu northeast and Zhaoqing west reaches 23 590, accounting for only 29%. Meanwhile the total number of extreme precipitation events in coastal areas reaches 55 315,accounting for 68%. Extreme precipitation shows a decreasing trend from coast to interior, and the occurrence of extreme precipitation along the coast is far greater than that in interior regions. The extreme precipitation is less in the east,west and north,but more in the middle and south. The extreme precipitation decreases from south to north in a band shape. The research results can provide new discoveries for the analysis of the characteristics of extreme precipitation changes in Guangdong Province and provide theoretical references for the formulation of water resources management and flood control strategies adapted to climate change.
