气候模型显示2026年厄尔尼诺现象有望成为有记录以来最强
多个气候模型预测,当前的厄尔尼诺事件将成为有记录以来最强的一次,预测普遍显示其将在2026年11月左右达到峰值,较平均值高出约4.0摄氏度,远超2015年创下的纪录。

多个气候模型预测,目前正在发展的厄尔尼诺事件在今年晚些时候达到峰值时,将成为有记录以来最强的一次。综合预测显示,作为衡量厄尔尼诺强度关键指标的Nino-3.4区域温度,将在2026年11月左右比平均值高出约4.0摄氏度。这将超过此前于2015年11月创下的纪录——当时该纪录比平均值高出3.08摄氏度,曾被视为有记录以来最强的厄尔尼诺事件之一。部分单独模型模拟结果显示,峰值甚至可能高达4.1至4.6摄氏度。
气候科学家将这一预计超越此前纪录约1摄氏度的幅度称为异常巨大,并指出这一差距已超过过去150年间记录到的最强与第五强厄尔尼诺事件之间的整个差距。这种异常的规模已引发与历史上少数几次特殊事件的比较,并促使研究人员密切关注该现象在未来几个月的发展情况。
厄尔尼诺现象由热带太平洋海面温度高于平均水平所驱动,已知会扰乱全球多个大陆的天气模式,包括降雨、干旱和风暴活动。由于该事件预计将在2026年末达到峰值,科学家表示,随着这一异常现象在全球气候系统中逐步显现,其广泛的气候影响很可能在随后的几个月里逐渐显露出来。
Key facts
- Climate models project the 2026 El Nino will become the strongest on record.
- Consensus forecasts show a peak of roughly 4.0C above average in the Nino-3.4 region around November 2026.
- The previous record was 3.08C above average, set in November 2015.
- Some model runs project peaks as high as 4.1 to 4.6C above average.
- The projected margin over the prior record exceeds the entire gap between the 1st and 5th strongest El Nino events in 150 years.
