Key Details:

EL NINA is the opposite phase of EL NINO in the EL NINO-Southern Oscillation (ENSO) cycle.
While EL NINO is characterized by a warming of the central and eastern tropical Pacific Ocean, LA NINA is marked by cooler-than-average sea surface temperatures in the same region.
During LA NINA, the trade winds become stronger, pushing warm water further west toward Asia. This allows for increased upwelling of cold, nutrient-rich water from the deep ocean to the surface along the American coast, further enhancing the cooling effect.
