月、年值曲线的比较表明，平流层风和厄尔尼诺-南方振荡(ENSO)参数的演变是不同的，它们之间可能没有关系。1997-98年厄尔尼诺现象在1997年2月至3月突然开始，并没有特别偏离那几个月的风变化的总趋势。1979年至今的谱分析表明，风场的显著变化是近2.40a的准两年振荡(QBO)，而ENSO的主要周期在3.7年和5.0年附近，在2.50年附近有一个小的QBO，与风QBO略有不同。版权所有©2004英国皇家气象学会
A comparison of the plots of the monthly and yearly values indicates that stratospheric winds and El Niño–southern oscillation (ENSO) parameters evolve differently and probably have no relationship with each other. The sharp commencement of the 1997–98 El Niño in February–March 1997 was not accompanied by any particular deviation from the general trend of the wind variation in those months. Spectral analysis for 1979 up to the present indicates that winds have only a quasi‐biennial oscillation (QBO) near 2.40 years as a prominent variation, whereas ENSO has main periodicities near 3.7 and 5.0 years and a small QBO near 2.50 years, slightly but significantly different from the wind QBO.
