就美国而言,NOAA预测专家说当前的拉尼娜现象“很可能会让美国南部今年冬天更为干旱、温暖,却使得西北部太平洋地带和北部地区更为潮湿、阴冷。”CPC副主任麦克•哈尔佩特说:“今年冬天,拉尼娜很可能会让美国南部持续干旱,或者加重那里的旱情。”
Fortunately, the current La Niña is weak and is expected to stay that way through the winter. This should keep the impact from being as severe as what was seen globally with 2015's record-setting El Niño, which saw deadly drought in Asia and helped make it the hottest year on record.
幸运的是,目前的阿尼娜现象较弱,而且据预测整个冬天都会保持这种态势,这样应该就不像2015年破纪录的厄尔尼诺那样造成严重后果:导致亚洲受到旱灾的致命重创,并让那2015成为有史以来最热的一年。
La Niña generally tends to lower global temperatures as it cools the surface of the tropical Pacific Ocean. It will be interesting to see if this La Niña can slow down the rapidly rising global temperatures and prevent 2016 from outpacing 2015 and becoming the third consecutive hottest year for the planet.
拉尼娜一般会让全球气温变冷,因为它会使热带太平洋表面水温下降。有意思的是,此次拉尼娜现象或许能够减缓正在快速上升的全球气温,并防止2016年气温高于2015年,接过前两年的接力棒,成为第三个最热年份。
