El Niño/La Niña Update (September 2012)
عرض التقرير
Neutral conditions (neither El Niño nor La Niña) continue in the tropical Pacific. During July
and August 2012, the tropical Pacific sea surface temperature rose to a level indicative of a
weak El Niño, but an atmospheric response has not yet been observed in the Pacific region.
An atmospheric response is necessary for an El Niño to have global climate impacts.
