Next result ,The correlation between rainfall variability over Thailand is linked to ENSO.
The Nino 3.4 SST index is the 5-month running mean in Nino 3.4 region .So We determined the correlation between this index and our standardized principal component smoothed using the 5-months running mean. It was found The correlation coefficient is -0.1651 It is negative, because a high SST anomaly gives a low Rainfall anomaly, and a low SST anomaly gives a high rainfall anomaly.
