El Niño/La Niña Update (November 2012)

Neutral conditions (neither El Niño nor La Niña) have continued in the tropical Pacific 

through recent months. Between July and September 2012, the tropical Pacific sea surface 

temperature increased to weak El Niño levels, but because the overlying atmosphere failed 

to respond (i.e., sea level pressure, wind and cloud patterns were near normal), overall 

conditions remained neutral.
