Abstract
The anomalous change in SST of June with reference to May studied for the Indian Ocean region (0–120°E, 40°S–40°N) during 1998 to 2005. The change in monthly SST anomaly in the equatorial region were studied along with changes in water vapor and wind field in 1998 and 2002, the years that representing contrasting changes in the summer monsoon rainfall. The westward extending equatorial warm pool in the Indian Ocean was found relative weak and found relatively weak during 1998 in contrast to those in 2002. Similar analysis further extended till 2005 indicated further the influence of the equatorial warm pool on the summer monsoon rainfall over the Indian subcontinent.
