对热带太平洋海表经向风应力异常与 Ｅ１ Ｎｉ ｏ事件之间的关系进行了诊断分析。结果表明，超前的经向风应力距平场与ＮＩＮＯ３区（１５°－９０°Ｗ，５°Ｓ－５°Ｎ）的海面温度异常（ＳＳＴＡ）有显著的超前相关，这种相关性在超前６个月甚至更早一些就有显示。利用奇异值分解方法分析超前的经向风应力距平场与太平洋海表温度异常场之间的耦合模，结果表明对应于赤道中东太平洋的海面温度异常升高，大气风应力场在超前６个月甚至更早的时候，在赤道中东太平洋表现为辐合的经向异常风应力场，即赤道以北为北风异常应力，赤道以南为南风异常应力。这种耦合模的时间系数与 ＮＩＮＯ３ ＳＳＴＡ指数所表示的 ＥＩｉｏ事件有很好的对应关系，表明这种耦合模反映的正是超前的经向风应力异常与 Ｅｌ ＮｉＢ ｏ事件所对应的海表温度异常之间的相关核态。通过与热带西太平洋纬向风应力异常的比较，赤道中东太平洋辐合的经向风应力异常与ＥｌＮｉｆｉｏ事件发生的同样具有重要的联系。
The diagnostic analysis of the relationship between the meridional wind stress anomalies in the tropical Pacific and the E1 Ni o events was carried out. The results show that the antecedent meridional wind anomaly field has a significant lead-time correlation with the SSTA in the NINO3 region (15 ° -90 ° W, 5 ° S-5 ° N) 6 months or even some have shown. Using the singular value decomposition method to analyze the coupled modes between the antecedent wind stress anomaly field and the Pacific anomalous surface temperature anomalies, the results show that the sea surface temperature corresponding to the equatorial central and eastern Pacific anomalies increases, the atmospheric wind stress field ahead of 6 Even months earlier, the anomalous wind stress field converged in the equatorial central and eastern equatorial Pacific shows abnormal north-equatorial stress to the north of the equator and south-equatorial anomaly to the south of the equator. The time coefficient of this coupled mode has a good correspondence with the EIio event represented by the NINO3 SSTA index, indicating that this coupling mode reflects precisely the advanced sea wind stress anomalies and the El NiB o event Correlated nuclear states between table temperature anomalies. By comparing with the zonal wind stress anomalies in the tropical western Pacific, the meridional wind stress anomalies converging in the equatorial central and eastern equatorial region are also of equal importance to those of the El Nifio event.
