| 摘 要： | 利用吉林省50站1951-2007年逐日降水资料,对暴雨的时空分布规律和气候变化特征进行了分析,对单站暴雨采用等级、序位、异常气候重现期等方法进行了评估.结果表明:吉林省暴雨一般集中出现在7月上旬到8月下旬,且有一半以上的县市暴雨的气候倾向率呈上升的趋势,1980s中期以来,吉林省中东部地区暴雨出现次数处于偏多阶段.对吉林省单站暴雨采用等级、序位、异常气候重现期等方法进行了评估,对2005-2007年吉林省出现的大暴雨进行了试评估. |

| Abstract: | Using the daily precipitation data of 50 meteorological stations in Jilin province from 1951 to 2007, temporal and spatial distributions and climatic change characteristics of the single-station heavy rainfalls are analyzed. The single-station heavy rainfalls are evaluated with some indices such as grades, orders and return period of abnormal climate. The results show that heavy rainfalls mainly occur from early July to late August in Jilin province. And the climatic trend rates of heavy rainfall show a raise tendency at more than half of the stations. The heavy rainfall events are more frequent in middle-east area of Jilin Province since the middle of 1980s. The single-station heavy rainfalls in Jilin province are evaluated with some indices such as grades, orders and return period of abnormal climate.The preliminary evaluating of heavy rainfalls exceeding 100 mm in Jilin province from 2005 to 2007 are given. |
