A directed climate network is constructed by Granger causality analysis of air temperature time series from a regular grid covering the whole Earth. Using winner-takes-all network thresholding approach, a structure of a smooth information flow is revealed, hidden to previous studies. The relevance of this observation is confirmed by comparison with the air mass transfer defined by the wind field. Their close relation illustrates that although the information transferred due to the causal…

Virtual Control Volume Approach to the Study of Climate Causal Flows: Identification of Humidity and Wind Pathways of Influence on Rainfall in Ecuador
Unraveling the relationship between humidity, wind, and rainfall is vitally important to understand the dynamics of water vapor transport. In recent years, the use of causal networks to identify…
Spatial organization of connectivity in functional climate networks describing event synchrony of heavy precipitation
TLDR
An analysis of the effects of event declustering on the resulting functional climate network properties describing spatio-temporal patterns of heavy rainfall events during the South American monsoon season based on ES and a conceptually similar method, event coincidence analysis (ECA).
A Novel Information Theoretical Criterion for Climate Network Construction
TLDR
The proposed approach based on the SODCC algorithm and the KLD constructs CNs with an emergent behaviour according to underlying wind speed prediction data physics, unlike the correlation-based method that produces spurious and missing links.
A causal flow approach for the evaluation of global climate models
TLDR
An Evaluation of Models by Causal Flows (EMCaF) is proposed, which aims to assess the weaknesses and strengths of GCMs to represent climate mechanisms and processes that couple different components of the climate system.

Unraveling spatio-temporal climatic patterns via multi-scale complex networks
The climate is a complex dynamical system involving interactions and feedbacks among different processes at multiple temporal and spatial scales. Although numerous studies have attempted to…
Optimal design of hydrometric station networks based on complex network analysis
TLDR
A new node-ranking measure – the weighted degree–betweenness (WDB) measure – is proposed that effectively quantifies the importance of rain gauges, although the benefits of the method need to be investigated in more detail.
Introduction to Focus Issue: Complex network perspectives on flow systems.
TLDR
This Focus Issue presents a collection of contributions addressing the description of flows and associated transport processes from the network point of view and its relationship to other approaches which deal with fluid transport and mixing and/or use complex network techniques.

The architecture of the climate network
Emergence of El Niño as an autonomous component in the climate network.
TLDR
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.
