| 摘 要： | 对1951—2000年的ENSO事件对松花江流域夏季(6—8月)降水的影响进行了分析,结果显示:赤道中东太平洋海温异常与松花江流域夏季降水有很好的相关性,特别是ENSO事件出现后,El Nino事件影响年通常对应于松花江流域夏季降水偏多,La Nina事件影响年松花江流域夏季降水则较常年偏少,且二者通过了置信度α=0.05的显著性检验.这种相关性可用于进行松花江流域夏季降水的预测.

| Abstract: | The effect of ENSO event for the period 1951 to 2000 on the summer precipitation(June to August) in Songhua River basin are studied.The results are summarized as follows:the summer precipitation in Songhua River basin has the very close relations with the middle east Pacific sea surface temperature anomaly.It is rather significant after the year of ENSO event.Songhua River basin tends to be more(or less) precipitation than its normal in summer as whole in El Nino(or La Nina).The correlation coefficients of ... |
