Tsallis' statistics in the variability of El Nio/Southern Oscillation during the Holocene epoch

Abstract

Analysis of the Tsallis q-triplet for the variability of El Nio Southern Oscillation (ENSO) index during the Holocene epoch (last 11,000 years) is presented. Three periods are analyzed, 07000, 70009700, 970011,000 years before the present. During the first and the third periods, the q-index values have the expected usual relations between them (qsens<1< qstat qrel).
