| 摘 要： | 根据1958—1997年越南降水资料和NCEP／NCAR再分析资料，运用小波分析和相关分析等方法分析了越南北部降水特征及其与海温的联系。结果表明，越南北部降水主要集中在夏秋季；越南北部夏秋季降水具有明显的年际、年代际变化特征．并且与热带太平洋海温关系密切。在越南北部夏季多雨年，热带西太平洋海温异常偏高，中东太平洋海温异常偏低；而少雨年，则情况相反。

| Abstract: | Based on the NCEP/NCAR reanalysis monthly data,by means of correlation analysis and the Mexico Hat Wavelet analysis,the variation features of rainfall in Vietnam and its relation to Pacific SSTs are studied.It is found that the precipitation mainly happens in summer and autumn;the summer and autumn precipitation has interannual and interdecadal variabilities.Further study shows that the summer rainfall in North Vietnam has a close relation with Pacific SSTs.When the summer rainfall is more(less),the SST is higher(lower) in the west Pacific Ocean and lower(higher) in the east-central Pacific. |
