| 摘要: |
| 南海不仅蕴藏着丰富的海底石油和各种矿产,而且还是海上重要航道，具有政治、军事和经济的特殊地位。它处于菲律宾、马来西亚和中南半岛三面陆地的环抱之中，东边与热带西太平洋边缘接壤，是一个半封闭的深水海域，既受陆地影响，又与邻近海域有关联，具有独特的海洋环境特征。由于南海为低纬热带海洋，而且处于季风气流上游，因此是我国夏季降水的水汽和各种能量的重要源地之一。它的海温变化与季风环流的相互作用以直接影响我国东部低纬地区的降水量。因此，研究南海海温的变化特征及其与El Nino的关系，不仅是研究该海域海洋环境预报的重要课题，而且可为中国南方天气与气候及其预测的研究提供重要依据.
本文在分析南海海温与赤道太平洋海温长期趋勢的基础上，采用了典型相关分析方法研究两海区的遥相关，并重点对南海滞后赤道东太平洋海温12个月的两海区前两对典型变量的交叉谱进行了分析。 |

| Abstract: |
| This study of the teleconnections between South China Sea SST and equatorial eastern Pacific were studied by using the canonical correlation analysis showed that the relationships were closest when South China SST lagged equatorial eastern Pacific SST by twelve months. As a result of the South China Sea SST’s response to the El Nino events. The coefficients of the canonical correlation variation between the SST of the two sea regions were studied by using cross-spectrum analysis. The results showed that the two regions have period of about quasi-2 years, 3-4 years and 16.7 years. |
