摘要：
近年来，极端天气事件激增，凸显出针对气候紧急情况采取行动的迫切需要。2023年出现了破纪录的全球气温、欧洲前所未有的热浪、亚洲毁灭性的洪水以及北美和澳大利亚严重的野火。超级厄尔尼诺事件以其对全球天气的深远影响而闻名，在这些变化中发挥着关键作用，造成严重的经济和环境损害。本研究提出了一种新型预测模型，该模型系统地整合局地和全球气候信号以预测超级厄尔尼诺事件，并引入了超级厄尔尼诺指数（SEI），其值达到80或更高即定义为一次超级厄尔尼诺事件。我们的分析表明，SEI准确反映了过去的超级厄尔尼诺事件，包括1982-83年、1997-98年和2015-16年的事件，这些时期的SEI值在2-sigma标准差内包含80。利用截至2022年的数据，我们的模型预测2023年SEI约为80，表明2023-24年期间将出现超级厄尔尼诺。近期观测证实，2023-24年厄尔尼诺是有记录以来历史上五次最强超级厄尔尼诺事件之一。对1982年至2023年SEI趋势的分析显示其逐渐上升，近期厄尔尼诺事件的SEI值持续超过70。这一趋势表明，厄尔尼诺事件正日益接近超级厄尔尼诺强度，可能是由于赤道太平洋出现了更有利的条件。SEI值的上升以及更强厄尔尼诺事件的频率增加，可能归因于全球变暖的持续影响。这些发现强调，有必要加强准备和战略规划，以减轻未来超级厄尔尼诺事件的影响；在未来几十年中，这类事件可能会变得更加频繁。
英文摘要：
In recent years, extreme weather events have surged, highlighting the urgent need for action on the climate emergency. The year 2023 saw record-breaking global temperatures, unprecedented heatwaves in Europe, devastating floods in Asia, and severe wildfires in North America and Australia. Super El Niño events, known for their profound impact on global weather, play a critical role in these changes, causing severe economic and environmental damage. This study presents a novel predictive model that integrates systematically local and global climatic signals to forecast Super El Niño events, introducing the Super El Niño Index (SEI), which value of 80 or higher defines a Super El Niño event. Our analysis shows that the SEI accurately reflects past Super El Niño events, including those from 1982-83, 1997-98, and 2015-16, with SEI values for these periods containing 80 within the 2-sigma standard deviation. Using data up to 2022, our model predicted an SEI of around 80 for 2023, indicating a Super El Niño for the 2023-24 period. Recent observations confirm that the 2023-24 El Niño is among the five strongest recorded Super El Niño events in history. An analysis of SEI trends from 1982 to 2023 reveals a gradual increase, with recent El Niño events consistently exceeding SEI values of 70. This trend suggests that El Niño events are increasingly approaching Super El Niño intensity, potentially due to more favorable conditions in the equatorial Pacific. This increase in SEI values and the frequency of stronger El Niño events may be attributed to the ongoing effects of global warming. These findings emphasize the need for heightened preparedness and strategic planning to mitigate the impacts of future Super El Niño events, which are likely to become more frequent in the coming decades.
