Experts: El Niño Could Be the Strongest on Record
Weather experts say this year could be one of the strongest El Niño events in recorded history.
Experts say El Niño could cause severe weather conditions in many parts of the world.
El Niño is Spanish for “the child.” It usually begins in December.
El Niño develops when winds off the west coast of South America weaken. This permits warm water in the western Pacific to expand toward the east. At the same time, clouds and rain over the warm water move east, too.
El Niño conditions normally appear only about two times every 10 years. Usually, El Niño conditions continue for about 12 to 18 months. They bring warm weather to some areas. These areas become wetter than normal, while others become drier.
Weather changes caused by El Niño depend on the strength of the condition.
Tom Di Leberto is a meteorologist at the National Oceanic and Atmospheric Administration in Washington, D.C. He says this year could be the third strongest El Niño on record.
