Significance El Niño, one of the strongest climatic phenomena on interannual time scales, affects the climate system and is associated with natural disasters and serious social conflicts. Here, using network theory, we construct a directed and weighted climate network to study the global impacts of El Niño and La Niña. The constructed climate network enables the identification of the regions that are most drastically affected by specific El Niño/La Niña events. Our analysis indicates that the…

Constructing regional climate networks in the Amazonia during recent drought events
- Environmental SciencePloS one
- 2017
The results suggest that hub nodes in the regional climate network of Amazonia have fewer long-range connections when more severe drought conditions appeared in 2010 than that in 2005, which is because of the dual roles played by both the Pacific and Atlantic oceans.
Complexity-based approach for El Niño magnitude forecasting before the spring predictability barrier

An approach relying on information entropy, which achieves some doubling of the prewarning time and facilitates long-term forecasting of the El Niño magnitude, and can potentially also be used as a measure for the complexity of other natural or engineering complex systems.

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.
