We use ordinal patterns and symbolic analysis to construct global climate networks and uncover long-and short-term memory processes. Data analyzed are the monthly averaged surface air temperature (SAT field), and the results suggest that the time variability of the SAT field is determined by patterns of oscillatory behavior that repeat from time to time, with a periodicity related to intraseasonal oscillations and to El Nino on seasonal-to-interannual time scales.
