Pre-summer monsoon (March-to-May, MAM) monthly rainfall anomalies fluctuated from -
204 to 373 mm for mainland stations and from -137 to 1474 mm for southern east coast
stations. These anomalies clearly related to all ENSO signals in January to March (JFM).
High La Nina signals (negative MEI, Nino1+2, Nino3, Nino4, and Nino3.4 and positive SOI)
in JFM were found with high pre-summer monsoon rainfall anomalies and El Nino was with
reverse effect. This relationship was more pronounced (r = 0.25 to 0.45) over the Northeast
(see Figure 4 MAM). Rainfall anomalies in post-summer monsoon months (September to
November, SON) were from -254 to 453 mm for mainland stations and from -496 to 1,108
mm for southern east coast stations. The positive (negative) SON anomalies were likely
found with high positive (negative) SOI, suggesting La Nina (El Nino), occurring in previous
six months, MAM. This relationship was stronger over central Thailand with r = 0.36 to 0.50
(see Figure 4 SON).
