造成气候变化的最重要因素是厄尔尼诺南方涛动,它可能在地球仪的不同地区引发灾害。尽管它的重要性,传统的预测仍然局限于提前6个月。最近,我们开发了一种基于网络分析的方法,该方法允许预测厄尔尼诺事件提前约1年。在这里,我们表明,我们的方法正确地预测了2012年和2013年没有厄尔尼诺事件,现在宣布,我们的方法表明(在2013年9月已经)厄尔尼诺在2014年底回归的可能性为3/4。我们还讨论了下一个厄尔尼诺现象的相关性,全球变暖的问题和目前的全球平均表面温度的间隙。
The most important driver of climate variability is the El Nino Southern Oscillation, which can trigger disasters in various parts of the globe. Despite its importance, conventional forecasting is still limited to 6 mo ahead. Recently, we developed an approach based on network analysis, which allows projection of an El Nino event about 1 y ahead. Here we show that our method correctly predicted the absence of El Nino events in 2012 and 2013 and now announce that our approach indicated (in September 2013 already) the return of El Nino in late 2014 with a 3-in-4 likelihood. We also discuss the relevance of the next El Nino to the question of global warming and the present hiatus in the global mean surface temperature.
