摘要
使用ＥＯＦ分析方法对２０年热带太平洋地区风应力场资料和ＳＳＴＡ资料进行分析，研究它们的空间分布特征模态和时间变化特征，发现风应力场的第一特征向量与海温距平场的第一特征向量的时间系数具有相同的变化特征。它们反映了海洋和大气在这个时空尺度上的相互作用和耦合关系，并与ＥｌＮｉｎｏ循环有较好的对应关系。
Twenty years of wind stress and SSTA data for the tropical Pacific are studied by the EOF method so that the characteristic modes of spacial distribution and features of temporal variation are revealed.It was shown that the first eigenvectors of both the field of wind stress and sea temperature have the same features of variation,representing the interaction and coupling relationship at this temporal and spacial scale between the ocean and atmosphere and being consistent with the El Nino cycle.
