摘　　要：利用长白山地区20个气象站点（1960~2009年）月平均降水量与全球海温SST（1960．2009年）逐月平均做相关分析和SVD分析。相关分析的结果表明：超前5月北太平洋海域海温与长白山地区降水存在显著相关关系。由SVD的第一模态异性相关系数分布表明：与长白山地区降水存在相关的关键海域为北太平洋东部地区，并与长白山全城存在较好的耦舍正相关。说明：当关键海域的海温偏暖（冷）时，滞后5月的长白山地区降水偏多（少）。Using average monthly rainfall in the 20 meteorologicai stations in the Changbai mountain area（1960 to 2009） and average monthly sea surface temperatu~ SST（1960 to 2009） with the correlation and SVD analysis. Correlation analysis showed that： in May ahead of the North Pacific Ocean sea surface temperature and precipitation in Changbai mountain area there was a significant correlation. The f＇wst mode of the SVD analysis showed that： the key region lies in the eastern of the North pa- cific Ocean which influences the Precipitation of Changbai mountain area and North pacific area have a good positive correlation coupling with the whole Changbai mountain are~. It description that： when the temperature of the key area in the North Pacific Ocean is warm（cold）, then the lag 5 month precipitation of Changbai mountain area would more（less）.
