Global climate network evolves with North Atlantic Oscillation phases: Coupling to Southern Pacific Ocean

We construct a network from climate records of the atmospheric temperature at the surface level, at different geographical sites in the globe, using reanalysis data from years 1948-2010. We find that the network correlates with the North Atlantic Oscillation (NAO), both locally in the North Atlantic, and through coupling to the Southern Pacific Ocean. The existence of tele- connection links between those areas and their stability over time allows us to suggest a possible physical explanation for this phenomenon. Copyright (C) EPLA, 2013
