Using observed sea surface temperature data from 1871-1998, and observed wind data from 1958-1998, we have confirmed that the recently discovered Indian Ocean Dipole (IOD) is a physical entity. Many IOD events are shown to occur independently of the El Niño. By estimating the contribution from an appropriate El Niño index based on sea surface temperature anomaly in the eastern Pacific, we have shown that the major fraction of the IOD Mode Index is due to the regional processes within the Indian… CONTINUE READING
