Abstract

We introduce a graph-theoretical framework for studying the interaction structure between sub-networks embedded within a complex network of networks. This allows us to quantify the structural role of single vertices or whole sub-networks with respect to the interaction of a pair of subnetworks on local, mesoscopic, and global topological scales. Climate networks have recently been shown to be a powerful tool for the analysis of climatological data. Here we use the concept of network of networks by introducing climate subnetworks representing different heights in the atmosphere. Parameters of this network of networks, as cross-betweenness, uncover relations to global circulation patterns in oceans and atmosphere. The global scale view on climate networks offers promising new perspectives for detecting dynamical structures based on nonlinear physical processes in the climate system. References Arenas, A., A.
