We construct and analyze a climate network which represents the interdependent structure of the climate in different geographical zones and find that the network responds in a unique way to El Niño events. Analyzing the dynamics of the climate network shows that when El Niño events begin, the El Niño basin partially loses its influence on its surroundings. After typically three months, this influence is restored while the basin loses almost all dependence on its surroundings and becomes autonomous. The formation of an autonomous basin is the missing link to understand the seemingly contradicting phenomena of the afore-noticed weakening of the interdependencies in the climate network during El Niño and the known impact of the anomalies inside the El Niño basin on the global climate system.
我们构建并分析了一个气候网络，该网络表示不同地理区域气候之间的相互依存结构，发现该网络对厄尔尼诺事件的响应具有独特的方式。分析气候网络的动态表明，当厄尔尼诺事件开始时，厄尔尼诺海盆部分失去了对周围环境的影响。通常三个月后，这种影响得到恢复，而海盆几乎失去了对周围环境的所有依赖，变得自主。形成一个自主的海盆是理解厄尔尼诺期间气候网络中相互依存关系明显减弱和厄尔尼诺海盆内部异常对全球气候系统的已知影响这两个看似矛盾现象的缺失环节。
