Alternating mutual influence of El-Nino/Southern Oscillation and Indian monsoon

Interdependence between El-Nino/Southern Oscillation and Indian monsoon is analyzed with the use of Granger causality estimation from data for the period 1871-2006. Four different versions of the Nino-3 and Nino-3.4 index are used to check robustness of the results. We reveal a non-symmetric bidirectional and even alternating character of coupling that extends previous knowledge about the presence of negative correlation and intervals of phase synchrony between the processes.
