LINC Working Points and their Topics

WP1: Network Construction and Analysis


We intend to improve and develop techniques for the reconstruction of complex networks from multidimensional climatological data. For this there are important methodological problems to solve because observations from the Earth system are typically rather short, noisy, and far from being stationary. The specific objectives of WP 1 are.

WP2: Interacting Networks

We propose to develop a framework for studying interacting networks. It will consist of various well- defined models of network interactions, new tools for characterisation and classification of coupled networks, simulation and numerical methods, as well as analytical tools based on percolation theory and generating functions for studying the robustness of interacting networks.

WP3: Natural Climate Variability

We aim to establish a theory that connects changes in network properties to specific physical processes of climate variability on interannual-to-interdecadal time scales. An important issue in this part of LINC will therefore be to connect network characteristics and measures (e.g. closeness centrality, betweenness centrality) to specific physical processes, which provides coupling between WP3 and WP1).

WP4: Future Climate Change

In LINC we will use the huge CMIP5 data base together with stand-alone atmospheric GCMs to study mechanisms of atmospheric teleconnection and climate variability on inter-annual to inter-decadal time scales.

WP5: Tipping Points in the Climate System

An important topic in which the innovative introduction of network thinking in climatology can have important rewards is in the characterization of regime transitions in the climate systems. Methodologies to detect regime shifts in past time series have been developed, both in the climatic context and beyond.
