摘要
本文介绍奇异值分解方法的原理及其在分析两个要素场之间线性关系中的应用。并用其对冬季北大西洋地区海表温度与500百帕高度标准化距平进行分析。结果表明,冬季北大西洋地区海表温度主要分布型与该地区的大气遥相关型密切相关。理论分析和实际计算结果都表明,奇异值分解方法在分析两个要素场之间的线性关系是很有效的。
The Principle of Singular Value Decomposition(SVD)and itsapplication in the investigation of the linear relationship between twofields are examined.The SVD is employed to study the relationshipbetween SST and 500 hPa geopotential height standard anomalies overthe North Atlantic in winter months.The results indicate that the SSTpatterns are well correlated with the teleconnection patterns at the500 hPa height. It is shown that the method of SVD is very effective in studying the linear relationship between two fields.
