| 摘 要： | 对南极气温资料、环南极海冰资料、太平洋海温资料、厄尔尼诺和拉尼娜资料的模拟验证，发现厄尔尼诺事件发生与德雷克海峡海冰减少在时间上有对应关系。南极半岛海冰减少是太平洋环流速度减慢的原因，德雷克海峡的海冰起重要作用。这一综合检验结果给出以日食—厄尔尼诺系数预测厄尔尼诺事件的有效性和准确性。两年周期的太平洋海温振荡使日食与厄尔尼诺之间存在12～24个月的位相差。

| Abstract: | Through comparing the data of sea ice around the South Pole continent, temperature in Pacific Ocean, temperature in the South Pole continent, El Nino and La Nina events, a determined and egregious causality between El Nino phenomena and the sea ices in Drake Passage is recognized. The velocity in Pacific circumfluence becoming slower is caused by sea ice decrease around the South Pole continent and sea ices in Drake Passage play more important role than others. The validity and veracity of solar eclipse--El Nino coefficients are clear in El Nino events prediction. Biennial oscillation of the temperature in Pacific Ocean caused the 12 months24 months difference of phase between solar eclipse and El Nino. |
