发展中的厄尔尼诺现象已成为有记录以来强度最强的一次。1太平洋中东部关键地区9月19日的日均海面温度比历史平均值高3.05°C，打破了2015年创造的3.02°C的纪录。1尽管已经创下历史新高，这场厄尔尼诺预计还将在2026年末达到峰值。1英国气象局负责人Adam Scaife指出："发展中的厄尔尼诺将是一个前所未有的事件，在距离峰值还有数周时就已超越之前的纪录，这显示了这次厄尔尼诺的巨大规模。"1
这一极端气象现象已开始影响全球天气模式。1印度气象部门数据显示，截至9月22日西南季风降雨量比正常水平低15%。1大西洋地区的风暴活动也出现异常，2026年至今尚未出现飓风，创下卫星监测以来的最晚无飓风纪录。1科学家仍在评估厄尔尼诺创纪录强度对全球天气的实际影响是否与其强度成正比。1
A developing El Niño phenomenon has already surpassed the strongest on record, weeks ahead of its anticipated peak in late 2026.1 The central and eastern Pacific experienced average sea surface temperatures 3.05°C above historical norms on September 19, eclipsing the previous record of 3.02°C set in 2015.1
Scientists are currently assessing whether the magnitude of this climate event will translate proportionally into global weather impacts, though some anticipated effects have already begun materializing worldwide.1 According to India's Meteorological Department, southwest monsoon rainfall as of September 22 has fallen 15 percent below normal levels.1 Additionally, the Atlantic basin has yet to see a hurricane in 2026, marking the latest start to the Atlantic hurricane season since satellite monitoring began.1
Adam Scaife, head of the UK Met Office, characterized the situation as unprecedented: "This developing El Niño will be an unprecedented event, having already surpassed the previous record weeks before its peak, which demonstrates the enormous scale of this El Niño."1
