| 摘 要： | 利用金华市1961～2011年的年降水量和逐日降水量资料,分析梅雨特征量（梅雨起讫日期、梅雨期长度、梅雨量、梅雨强度）的基本统计特征及其相互关系,并在此基础上对梅雨汛期的年际和年代际变化、周期和变化趋势进行了研究,最后探讨了各梅雨特征量对厄尔尼诺（拉尼娜）年的响应。结果表明,金华市梅雨年际和年代际变化明显,大致存在22年的周期;厄尔尼诺年,金华市出梅偏迟,梅雨期长度偏长,梅雨量偏多,梅雨强度偏强;拉尼娜年,金华市梅雨量偏少,梅雨强度偏弱。

| Abstract: | Based on yearly precipitation and daily precipitation of Jinhua during 1961- 2011,the decadal scale variation characteristics of Meiyu time series were investigated by exploring characteristics of Meiyu spell（including the beginning date and the end date of Meiyu,period,amount and intensity）. And how the characteristics of Meiyu responded to the current year of El Nino event and the current year of La Nina event were discussed. The results showed that： The interannual and interdecadal variation of Meiyu in Jinhua were obvious,which showed that the periodic length was probably 22 years. In the current year of El Nino event,the end date of Meiyu delayed while the plum period length,the plum rains amount and the plum rains intensity were increasing. In the current year of La Nina event,amount and intensity were decreasing. |
