Abstract

Based on the monthly average SST and 850 hPa monthly average wind data

the seasonal

interannual and long-term variations in the eastern Indian Ocean warm pool (EIWP) and its relationship to the Indian Ocean Dipole (IOD)

and its response to the wind over the Indian Ocean are analyzed in this study. The results show that the distribution range

boundary and area of the EIWP exhibited obviously seasonal and interannual variations associated with the ENSO cycles. Further analysis suggests that the EIWP had obvious long-term trend in its bound edge and area

which indicated the EIWP migrated westwards by about 14 longitudes for its west edge

southwards by about 5 latitudes for its south edge and increased by 3.52×106 km2 for its area

respectively

from 1950 to 2002. The correlation and composite analyses show that the anomalous westward and northward displacements of the EIWP caused by the easterly wind anomaly and the southerly wind anomaly over the eastern equatorial Indian Ocean played an important and direct role in the formation of the IOD.
