The temperatures in different zones in the world do not show significant changes due to El Niño except when measured in a restricted area in the Pacific Ocean. We find, in contrast, that the dynamics of a climate network based on the same temperature records in various geographical zones in the world is significantly influenced by El Niño. During El Niño many links of the network are broken, and the number of surviving links comprises a specific and sensitive measure for El Niño events. While… Expand
Analysis of the structure of climate networks under El Niño and La Niña conditions
The El Nino-Southern Oscillation (ENSO) is the most important driver of natural climate variability and is characterized by anomalies in the sea surface temperatures (SST) over the tropical PacificExpand
Interpretation of link fluctuations in climate networks during El Niño periods
Recent work has shown that the topologies of functional climate networks are sensitive to El Ni?o events. One important interpretation of the findings was that parts of the globe act in correlatedExpand
ENSO teleconnections in the southern hemisphere: A climate network view.
TLDR
The differential response to extreme phases of ENSO during austral springtime is related to the forcing of waves of different tropical origins, as well as the prevalence of different intraseasonal regimes in each phase of E NSO. Expand
Forecasting the magnitude and onset of El Nino based on climate network
El Nino is probably the most influential climate phenomenon on interannual time scales. It affects the global climate system and is associated with natural disasters and serious consequences in manyExpand
Network analysis reveals strongly localized impacts of El Niño
TLDR
It is found that regions that are characterized by higher positive/negative network “in”-weighted links are exhibiting stronger correlations with the El Niño basin and are warmer/cooler during El Niño/La Niña periods. Expand
Oceanic El-Niño wave dynamics and climate networks
The so-called El Nino-southern oscillation (ENSO) is the most important and influential climate phenomenon of contemporary climate variability, in which oceanic wave dynamics plays an important role.Expand
Climate network and complexity based El Ni\~no forecast for 2021
The El Niño Southern Oscillation (ENSO) is the most important driver of interannual climate variability and can trigger extreme weather events and disasters in various parts of the globe. Recently,Expand
Very early warning of next El Niño
TLDR
An approach based on network analysis, which allows projection of an El Niño event about 1 y ahead, is developed and it is shown that this method correctly predicted the absence of El Niño events in 2012 and 2013 and now it is announced that the approach indicated the return ofEl Niño in late 2014 with a 3-in-4 likelihood.

Percolation Phase Transition of Surface Air Temperature Networks: A new test bed for El Niño/La Niña simulations
TLDR
The percolation phase transition is verified using three different reanalysis datasets, and is proposed as a new test bed, which deserves more attention in the future. Expand
Climate network structure evolves with North Atlantic Oscillation phases
We construct a network from climate records of temperature and geopotential-height in two pressure levels at different geographical sites in the North Atlantic. A link between two sites representsExpand
