    Abstract:

    [Objective] This paper elucidated the distribution characteristics of extreme precipitation events in Guangdong Province and made forecasts about the future trends in order to provide scientific basis for the study of climate assessment, ecological environment construction and sustainable economic development. [Methods] Based on daily precipitation data of 24 meteorological stations in Guangdong Province during 1960-2013, the extreme precipitation thresholds were determined for different stations by the centesimal value method, and then, frequency, intensity of extreme precipitation events were analyzed by using Mann-Kendall test method, wavelet analysis, the Hurst index to explore the trend of extreme precipitation events. [Results] The frequency, intensity and rainfalls of extreme precipitation events in Guangdong Province were increased. Extreme precipitation accounts for about 50 percent of the total precipitation. In space, the frequency of extreme precipitation events decreased from the north to the south, while the intensity showed opposite distribution. Extreme precipitation frequency and intensity were forested consistent with the ones of the past, showing continually increasing trend. [Conclusion] The frequent occurrence of extreme precipitation events caused serious losses to Guangdong Province. The province should strengthen the prevention of extreme events. Corresponding measures should be taken to deal with the extreme precipitation cases resulted from different causes.
