If you think you have heard enough about the growing “super” El Niño, trust me, you are going to hear a lot more. What is happening in the equatorial(赤道的) Pacific is jaw-dropping(令人瞠目结舌的) and could well mark one of the biggest global weather upheaval(剧变,动荡)s in a millennium. It will spawn a string of weather catastrophes around our world in what remains of this year and in 2027, and there is no reason to think the UK will be immune.(它将在今年剩余时间和2027年给全球带来一连串天气灾难,我们没有理由认为英国能独善其身。)
如果你以为自己已经听够了关于日益增强的“超级”厄尔尼诺的消息,相信我,你还会听到更多。赤道太平洋正在发生的事情令人瞠目结舌,很可能标志着千年一遇的最大全球天气动荡之一。它将在今年剩余时间和2027年给全球带来一连串天气灾难,我们没有理由认为英国能独善其身。
To recap(简要回顾) briefly, El Niño involves a heating of the central and eastern equatorial Pacific ocean. It happens every few years and is part of a natural cycle termed the El Niño southern oscillation(振荡,涛动), which switches between warm (El Niño) and cool (La Niña) phase(相位,阶段)s. El Niños that see heating reach or exceed 2C are defined as “super” but this one, which is forecast to top-out at an astonishing 4C later this year, is so much bigger, the term “hyper” might be more appropriate.(升温达到或超过2°C的厄尔尼诺被定义为“超级”,但这一次预计今年晚些时候将达到惊人的4°C,规模大得多,用“超级加倍”这个词或许更合适。)
简要回顾一下,厄尔尼诺现象涉及赤道太平洋中部和东部海水升温。它每隔几年发生一次,是被称为“厄尔尼诺南方涛动”的自然循环的一部分,该循环在暖相位(厄尔尼诺)和冷相位(拉尼娜)之间切换。升温达到或超过2°C的厄尔尼诺被定义为“超级”,但这一次预计今年晚些时候将达到惊人的4°C,规模大得多,用“超级加倍”这个词或许更合适。
El Niño is nothing new(并非新鲜事). Evidence for its existence extends back hundreds of millions of years and its ramification(后果,影响)s have always been negative and disruptive(破坏性的). The difference today is that it is happening at a time when our world is heating more rapidly than ever before, and it is being supercharged as a result, leading to increasingly extreme weather.(不同之处在于,它正发生在一个全球变暖速度前所未有的时代,因此威力大增,导致天气越来越极端。)
厄尔尼诺并非新鲜事。其存在的证据可追溯至数亿年前,其后果历来都是负面且具有破坏性的。不同之处在于,它正发生在一个全球变暖速度前所未有的时代,因此威力大增,导致天气越来越极端。
