Say bye bye to El Nino and hello to La na. Nina. NA Satellite data show the current El Nino, the most powerful yet recorded, is waning. The massive Pacific Ocean phenomenon occurs when vast tracts of the equatorial Pacific begin to warm, changing normal ocean currents and more importantly disrupting world weather patterns.
The US-French TOPEX/Posidon satellite, which studies the Pacific for El Nino-related changes, indicates the water is slowly cooling and normal current circulation is returning. It also shows the receding El Nino may be replaced by a La Nina, an event which only occasionally follows an El Nino. Researchers believe La Nina could activate by autumn, with drought replacing floods and new weather patterns.
