La Nina Ready Nations (LNRNs)

La Niña

A La Niña Ready Nation would be a nation that expects and prepares for extreme impacts during La Niña of weather, water and climate related hazards normally associated with ENSO-Neutral. During La Nina conditions, the east to west flow present during neutral conditions is intensified.Slide1

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.
