The Southern Oscillation and Indonesian sea surface temperature.

It is demonstrated that a simple ad hoc model representing a stochastically-forced, seasonally-varying interaction between the atmosphere and the ocean in the Indonesian region can produce simulated anomalies of Darwin pressure and Indonesian sea surface temperature that reproduce the observed statistical behaviour of these anomalies without the inclusion of the effects of oceanic and atmospheric events external to the Indonesian region. It suggested that the El Nino-Southern Oscillation might be the dynamic response of the Pacific Ocean and overlying atmosphere to anomalies produced by such an interaction in the Indonesian region. A speculation is raised involving the possible physical basis for such an interaction.-from Author
