with negative DJF rainfall anomaly over the southern east coast. Also, La Nino event in OND
was with more DJF rainfall. Moreover from Table 2, both ENSO and IOD strengths in OND
was equally associated with Thailand rainfall; whereas ENSO was dominant from January to
May and IOD was singly dominant in summer monsoon month (June to August, JJA). This
ENSO-IOD coexistence is consistent with the finding from the study on dipole variability of
sea surface temperature (SST) in the Indian Ocean, conducted by Baquero-Bernal et al.
(2002).
