Show affiliationsUsing measurements of atmospheric temperatures, we create a weighted network in different regions on the globe. The weight of each link is composed of two numbers —the correlations strength between the two places and the time delay between them. A characterization of the different typical links that exist is presented. A surprising outcome of the analysis is a new dynamical quantity of link blinking that seems to be sensitive especially to El Niño even in geographical regimes outside the Pacific Ocean.
