厄尔尼诺,几个听上去有些拗口又有些陌生的字眼,今年却频频见诸于报端。什么是厄尔尼诺?厄尔尼诺与我们有什么关系?恐怕会有许多人回答不上来。其实,厄尔尼诺对于我们并不陌生,20年来这种现象分别在正1976～1977年、1982～1983年、1986～1987年、1991～1993年和1994～1995年先后出现过5次。进入90年代后,随着全球变暖,厄尔尼诺现象出现得越来越频繁。厄尔尼诺现象的发现已有100余年的记载。有专家说:厄尔尼诺将是本世纪气象学上最重要的名词。它有可能引发全球的气候灾难。干旱所导致的农业减产、洪涝灾害带来的人员伤亡、全球气温的普遍升高,都与厄尔尼诺的出现有着直接的关系。厄尔尼诺就好像一辆达摩克利斯之剑而悬在全世界的头上。专家预计,目前的厄尔尼诺现象将一直持续到1998年初,它对我国长江流域以北和东北地区的气候产生了影响。本文将有助于读者了解什么是厄尔尼诺以及它给全球气候带来的负面影响等等。当然,任何事物都是有利有弊。比如厄尔尼诺现象所带来的暖冬,对农业生产、水资源的分配及人体健康都有一定的好处。或许,我们该重新认识它。
El Niño, a few words that sounds a bit stupid and strange, is often seen in the newspapers this year. What is El Niño What does El Niño have to do with you? I’m afraid many will not answer. In fact, El Niño is no stranger to us. In the past 20 years, this phenomenon has appeared five times successively in 1976-1977, 1982-1983, 1986-1987, 1991-1993 and 1994-1995. Into the 90’s, as global warming, El Niño phenomenon appears more and more frequently. The discovery of the El Niño phenomenon has been recorded for more than 100 years. Some experts say El Nino will be the most important term in meteorology in this century. It is likely to trigger a global climate disaster. Drought-induced agricultural cuts, casualties caused by floods and floods and the general increase in global temperatures are all directly related to the emergence of El Niño. El Nino is like a sword of Damocles hanging over the world. Experts predict that the current El Niño phenomenon will persist through early 1998 and have an impact on the climate in the areas north and northeast of the Yangtze River. This article will help readers understand what is El Niño and what it does to the global climate and so on. Of course, everything has pros and cons. For example, warm winter brought by the El Niño phenomenon has certain benefits to agricultural production, water resources allocation and human health. Perhaps, we should know it again.
