Numerical Simulation of the Interaction between Tropical Pacific and Indian Ocean in Different Periods

The CCM3 simulation results show that the interaction of El Nino upon Indian Ocean Dipole mode was very weak during the phase between 1930 and 1961. But from 1962 to 2001, Indian Ocean Dipole mode provided favorable conditions for Pacific warm events warm, the Walker circulation over the tropical Pacific and the vertical Zonal monsoon circulation over the tropical Indian Ocean coupled well at the Oceanic Continent. and also warm events in the Pacific provided favorable condition for Indian Ocean Dipole mode from 1962 to 2001.
