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.
