前 言 E1 Ni(?)o现象越来越引起人们的注意。因为E1 Ni(?)o现象经常伴随着出现全球大气的异常。E1 Ni(?)o年会使原来干旱的赤道东太平洋地带有强烈的降水。南美和北美沿岸也常造成洪水灾害。1982年强E1 Ni(?)o年中加利福尼亚的洪水造成了几亿美元的损失。而印度尼西亚和澳大利亚以及南非却会遭受持久的干旱。E1 Ni(?)o现象对我国的气候也有明显的影响,有人认为我国东北地区夏季的低温冷害和南方梅雨的多寡与E1 Ni(?)o现象有关。 近年来,对E1 Ni(?)o现象的研究已作了很多工作。本文试图对E1 i(?)o现象的研究概况作一简要的介绍。
Introduction E1 Ni (?) O phenomenon attracts more and more attention. Because E1 Ni (?) O phenomenon often accompanied by the emergence of the global atmosphere anomalies. E1 Ni (?) O annual will make the original drought in the equatorial eastern Pacific Ocean with strong precipitation. Floods are also often caused on the coasts of South America and North America. The floods of California in 1982 caused hundreds of millions of dollars in losses during the 1982 El Niño (?) O year. Indonesia and Australia, as well as South Africa, suffer prolonged droughts. E1 Ni (?) O phenomenon also has a significant impact on the climate in China. Some people think that the cold chilling in summer and the quantity of rainy days in the northeast of China are related to E1 Ni (?) O phenomenon. In recent years, much work has been done on the research of E1 Ni (?) O phenomenon. This article attempts to give a brief introduction to the research situation of E1 i (?) O phenomenon.
