El Niño and La Niña: Frequently asked questions
2016年1月18日 · El Niño and La Niña are the warm and cool phases of ENSO (pronounced “en-so”). ENSO is the most influential natural climate pattern on Earth. ENSO swings back and forth every few years. El Niño and La Niña affect both the ocean and the atmosphere. Periods of weaker- or stronger-than-average easterly trade winds initiate El Niño and La Niña.
