Resum
We study global climate networks constructed at various time-scales by means of ordinal time series analysis of surface air temperature (SAT) anomalies. We use re-analysis data from the National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) covering the last 70 years. To infer climate interdependencies, we use the mutual information computed from data values and from the symbolic, ordinal based representation. The latter allows identifying changes in...
