However, when surface waters are warm (as during an el ni? O), they do not allow the colder, deeper currents to upwell and effectively block the flow of life-sustaining nutrients.
可是，如果海面水温较高(例如在厄尔尼诺期间)，深层海水就无法上流，从而大大阻断了这些生命必须营养的正常循环。

在1997年和1998年间，因厄尔尼诺现象，即太平洋的不规律升温现象，发生了多次旱灾，在此期间，39000平方公里的亚马逊森林被类似的大火焚毁。

Please read the following article and find out what role El Ni?o and La Ni?a play.
请阅读以下文章，看一看厄尔尼诺和拉尼娜现象所起的作用。
Because of the el Ni? O and La Ni? A effects, and all those other factors, figuring out what might happen to hurricanes in a warmer world is, well, complicated.
由于厄尔尼诺和拉尼娜现象，以及所有其它的因素，要研究在全球变暖的情况下飓风的是很复杂的。
A related event, called an el Ni? O, happens when the waters become unusually warm.
另一种相关的现象被称为厄尔尼诺现象，当海水温度异常升高时就会发生。
Our experiments in which a Ni o system was used as the sample show that this method is very successful.
以镍氧体系作为样品的实验表明，该方法非常成功。
Like a vast climatic mailbag, el Ni? O-enhanced activity hand-delivers heat and moisture to parts of the globe where they would not normally go.
厄尔尼诺增强了这一活动，它象一个巨大的气候邮包，亲手把热量和湿气带到平常并不光临的地球部分地区。
A known instigator of storms, floods, droughts, and secondary effects like fires, the El ni? O-Southern Oscillation could go a long way toward explaining many weather extremes.
已知它激起风暴、洪水、干旱还有如火灾这样的副效应。厄尔尼诺向南摆动的现象对解释许多极端天气现象很有帮助。
Archaeological evidence suggests El Ni? O has been around for thousands, possibly millions of years.
考古学方面的证据表明，厄尔尼诺已存在了数千年，或许数百万年。
The Ni(II) cation has a distorted octahedral geometry defined by five N atoms from two dimethylglyoxime molecules and two O atoms from two formate anions.
镍离子与两个丁二酮肟配体上的四个氮原子和两个甲酸根离子上的碳原子配位进而形成八面体配位环境。
La Ni? A also makes weather conditions worse but rarely bullies as harshly as el Ni? O.
拉尼娜现象同样会使天气状况变糟，但很少象厄尔尼诺现象那样横行霸道。
"The Americas are greatly affected by El Ni? O," Trenberth says. "Europe is much less affected."
川伯斯说：“南北美洲受厄尔尼诺现象影响很严重，欧洲受的影响则要小得多。”
El Ni? O, the periodic warming of the equatorial Pacific that induces storms and other climatic events, historically occurs once every three to seven years and lasts for up to two years.
厄尔尼诺是赤道附近的太平洋周期性变暖现象，引发风暴和其它气候事件，历史上每三至七年发生一次，持续时间可长达两年。
In addition, the climate warming would produce the significant impact on the global water cycle, and make the El ni o respond increase, and give rise to the more and abnormal climate catastrophe.
另外，气候变暖还可能对全球水循环产生重大影响，使厄尔尼诺效应加剧，引发更多的异常气候灾难。
In addition, the climate warming would produce the significant impact on the global water cycle, and make the El ni o respond increase, and give rise to the more and abnormal climate catastrophe.
