Global Climate Networks & Significant El Niņo Effects Significant temperature changes due to El Niņo have only been detected in different parts of the world when they were measured in a restricted area of the Pacific Ocean. The authors found that, based on the same temperature records from various geographical zones around the world, the dynamics of a climate record is significantly influenced by El Niņo. Many links of the network are broken during an El Niņo event, a specific and sensitive measure of El Niņo events is comprised of the number of links that survive. These links, representing correlations between temperatures in different sites, are more stable, the links being broken during El Niņo periods by fast fluctuations of the correlations observed during these periods. Summary The authors1 have developed a method enabling the following of large changes over time of an underlying network structure that involves observing the fluctuations in the correlations between the nodes. Using this method blinking links, that appear and disappear over a short time period, are tracked, and this method assumes structural changes are the cause of this behaviour. Links with large time delays comprise the majority of links that break during El Niņo events.
