| Abstract: | Based on 740 stations of daily precipitation datasets in China, the precipitation- concentration degree (PCD)and precipitation-concentration period (PCP)ofdifferentintensity durative precipitation eventswere calculated to analyze theirstatisticalcharacteristics,mainly including spatial and temporaldistributions,variations and climatic trends ofthe two parameters ofthe durative heavy precipitation events in China.Itis proved thatthese two parameters ofheavy rainfallcan display the temporalinhomogeneity in the precipitation field.And itis also found thatthere is a good positive relationship between the precipitation-concentration degree and annualrainfallamountin the Eastern and CentralChina.Thismethod can beapplied in flood assessmentand climatechangefields. |
