| 摘 要： | 近年来,海表温度在中长期天气预报上应用较广泛,为了使这项工作更引深一步;同时,也为了开发海洋资源、航运和做好海温预报的需要,对影响海温距平场变化的因子进行研究,是有现实意义的.我们用自然正交分解法,对北太平洋(纬度范围取10°S-50°N,见图2)1949-1975年共27年的月平均海表面温度(下简称海温)距平场进行分解.这种分解法的优点是:自然正交函数不是事先给定的固定函数形式,而是由历史资料本身决定.因此它能反映出海温距平场的最主要特点,同时收敛性也比较快.如此,就容易抓住影响海温距平变化的主要因子,而物理意义也比较明确.

| Abstract: | In the article the monthly anomaly field of sea surface tempera ture of the North Pacific during 1949-1975 is resolved into natural orthogonal polynomials.An analysis of the relationship between several main eigenvectors of the polynomials,the weather conditions,and the centers of action in atmosphere indicates. |
