科学家修订了厄尔尼诺/拉尼娜分类,以反映海洋变暖,将气候变化与更强、更频繁的极端天气联系起来。 Scientists revised El Niño/La Niña classification to reflect warming oceans, linking climate change to stronger, more frequent extreme weather.

科学家们更新了厄尔尼诺和拉尼娜是如何分类的,原因是全球变暖迅速,从固定基线转向相对指数,导致海洋气温上升。 Scientists have updated how El Niño and La Niña are classified due to rapid global warming, shifting from fixed baselines to a relative index that accounts for rising ocean temperatures. 这一变化反映出世界正在变暖,传统的30年平均数不再代表正常情况。 The change reflects a warming world where traditional 30-year averages no longer represent normal conditions. 2020年至2023年间持续的拉尼娜将多余热量困在海洋中，这些热量在强烈厄尔尼诺期间释放，促成了2023年至2025年全球气温的创纪录。 A prolonged La Niña from 2020 to 2023 trapped excess heat in the ocean, which was released during a strong El Niño, contributing to record global temperatures from 2023 to 2025. 在增加的能源不平衡中,约75%是由于气候变化和这些阶段之间的转变造成的,23%与拉尼娜现象的延长有关。 About 75% of the increased energy imbalance stems from climate change and the shift between these phases, with 23% linked to the extended La Niña. 新系统可能导致减少厄尔尼诺现象的命名和更多的拉尼娜现象,更好地捕捉气候变化如何扩大自然循环,如何驱动飓风和干旱等极端天气。 The new system may result in fewer El Niño designations and more La Niña events, better capturing how climate change amplifies natural cycles and drives extreme weather like hurricanes and droughts.
