Topology and predictability of El Niño and La Niña networks.
TLDR
It is verified that indeed during El Niño years predictability is lower compared to La Niña years.Abstract:
We construct the networks of the surface temperature field for El Nino and for La Nina years and investigate their structure. We find that the El Nino network possesses significantly fewer links and lower clustering coefficient and characteristic path length than the La Nina network, which indicates that the former network is less communicative and less stable than the latter. We conjecture that because of this, predictability of temperature should decrease during El Nino years. Here we verify that indeed during El Nino years predictability is lower compared to La Nina years.read more

TL;DR: The success of new scientific areas can be assessed by their potential in contributing to new theoretical approaches and in applications to real-world problems as mentioned in this paper, and complex networks have fared extremely well in both these aspects, with their sound theoretical basis being developed over the years and with a variety of applications.

Complex networks in climate dynamics. Comparing linear and nonlinear network construction methods
TL;DR: The global scale view on climate networks obtained using mutual information offers promising new perspectives for detecting network structures based on nonlinear physical processes in the climate system.

A k-shell decomposition method for weighted networks
TL;DR: The method takes into account both the weight and the degree of a network, in such a way that in the absence of weights the authors resume the shell structure obtained by the classic k-shell decomposition, and in the presence of weights is able to partition the network in a more refined way.

TL;DR: Analysis of the atmospheric conditions that lead to these teleconnections confirms Rossby waves as the physical mechanism underlying these global teleconnection patterns and emphasizes their crucial role in dynamical tropical–extratropical couplings.

Analysis of spatial and temporal extreme monsoonal rainfall over South Asia using complex networks
TL;DR: In this paper, a detailed analysis of summer monsoon rainfall over the Indian peninsular using nonlinear spatial correlations is carried out employing the tools of complex networks and a measure of nonlinear correlation for point processes such as rainfall, called event synchronization.
