Southern Oscillation

  • Out-of-phase relationship between atmospheric pressure over the southeast Pacific and the Indian Ocean. When pressure is high in the Indian Ocean, it is lower than usual in the south Pacific Ocean. Rainfall varies in the opposite direction. The Southern Oscillation is closely linked to El Niño events.
