摘要: 厄尔尼诺、拉尼娜现象是国际社会普遍关注的问题.在参阅国内外科学研究成果的基础上,通过对厄尔尼诺、拉尼娜的基本概念和特征的描述,分析几种有代表性的成因机理,探讨厄尔尼诺、拉尼娜现象对全球气候特别是对我国气候的影响.最后提出了当前学术界存在的问题和今后努力的方向,并对未来的研究作了美好的展望.

Abstract: El Niйo and La Niйa are the phenomena concerned internationally. The author refers to all scientific research achievements at home and abroad, describes their basic notions and features, analyses and discusses several typical formative principles. Finally he concludes that the appearrance of El Niйo and La Niйa results from the unbalance of the air stream interaction on the sea no matter what kind of processes they are. Both El Niйo and in Niйa are not isolated, so they make global and peculiar influence on the climate even if they only appear on the 1/4 tropical sea surfaces. El Niйo mainly affects the distribution of drought and flood at a large scale, i. e. the flood on the east of the southern Pacific Ocean and the drought on the west of the Pacific Ocean and Africa. On the other hand, La Niйa disturbs the usual climate features of one area, i. e. originally there ought to be plenty of rain fall in a certain season or area, but now it is especially hot. Furthermore, it can deteriorate the climate feature, making the dry area drier and the wet place wetter. In the end, the article comments on the influnce of El Niйo and La Niйa on the climate of our country, analyses the existing problems at the present academic field and points out the prospects of our future work.
