Facts about ENSO Phenomenon

1. 06

   La Niña events typically bring increased hurricane activity in the Atlantic basin, while El Niño tends to suppress it through enhanced wind shear.

   During El Niño events, warmer-than-normal sea surface temperatures in the central and eastern tropical Pacific suppress upwelling, significantly reducing marine productivity along the South American coast.

   ENSO phenomenon cycles occur irregularly every two to seven years, making precise long-range prediction a major challenge in climate science.

   The ENSO phenomenon alternates between El Niño warm phases and La Niña cool phases, driven by coupled interactions between sea surface temperatures and trade winds in the tropical Pacific.
