La Niña

ENSO -> Seasonal Climate -> Impacts on Society

During La Nina conditions, the east to west flow present during neutral conditions is intensified.

This anomalous wind regime is responsible for anomalies in sea surface temperature; above average in the western Pacific and below average in the eastern Pacific. In accordance with the shifts in sea surface temperature, rainfall will be relatively higher in the western Pacific and relatively lower in the eastern Pacific.

During La Nina, the deviations of sea surface temperature and rainfall from normal are generally less dramatic than the deviations that occur during El Nino.

During La Nina, the following conditions are likely:
