The result , the lead-lag correlation between PC1 and the Nino3.4 of DJF
showsFor the ENSO, the lead-lag correlation between the rainfall variability and the Nino3.4
shows correlation coefficients are negative (Fig. 5b). The negative correlation between
the PC1 and Nino3.4 indicates the increasing (decreasing) of rainfall over the Indochina
