|Global effects ("teleconnections") of ENSO warm events.|
| The term El Niño
(Spanish for the Christ Child) was originally used by South American fisherman
to refer to especially warm ocean conditions that typically appear around
Christmas and occasionally last well into the summer. Catches decline markedly
during these warm periods, producing economic hardships not only for individual
fisherman, but also for entire nations such as Chile and Peru who depend
on fish for crucial export earnings. But the impacts of El Niño extend
far beyond the South American coast. As this map shows, El Niño events
produce ripples throughout the world's climate system. Ripples that occur
far away but seem to be related are known as teleconnection.
These teleconnections stretch across the globe, from flooding in the Peruvian
Andes and the southeastern United States, to severe drought in Indonesia
and central India, to voracious wildfires that hurtle across the forests
and brush of eastern Australia.
