北太平洋海温与福建后汛期降水量的关系

本文应用奇异值分解方法给出同期和前期北太平洋海温与福建后汛期降水量相互匹配的空间典型分布型．分析结果表明，无论同期还是前期北太平洋海温与福建后汛期降水量之间均存在着清晰的遥相关．同期的赤道中东太平洋海温异常增高、日本以东洋面海温偏低，福建后汛期降水量偏少；另外，闽南地区后汛期降水量与同期NINO西海区和黑潮海区的海温成正相关关系．冬、春季出现厄尔尼诺现象时，次年福建尤其是闽南沿海后汛期降水量将偏少．

Relation between sea surface temperature in north Pacific and summer precipitation in Fujian

With application of singular value decomposition (SVD) method, the study conducted on the spatial typical distribution patterns which were matched between the north Pacific sea surface temperature(SST) field from the previous to the corresponding periods and the summer precipitation in Fujian. The results show that the interconnection between the north Pacific sea surface temperature in the periods and the summer precipitation in Fujian is outstanding.When SST in the mid-ea-(stern) equatorial Pacific anomalously increases and SST to the east of Japan decreases in summer, Fujian summer rainfall drops. Otherwise, the normat correlation exists between the corresponding SST in west sea area of NINO and the Kuroshio and the summer rainfall in southern Fujian. When El Nino occurs in winter and spring, summer rainfall in Fujian especially in the southern Fujian coastland will decreases in the following year.
