   El Niño and La Niña are two opposing climate patterns that break these normal conditions. Scientists call these phenomena the El Niño-Southern Oscillation (ENSO) cycle. El Niño and La Niña can both have global impacts on weather, wildfires , ecosystems , and economies.

   What causes a switch between El Nino and La Nina?

   • We have demonstrated highly robust evidence that the switch between El Nino and La Nina is caused by an ocean subsurface wave propagating along thermocline from western Pacific to central and eastern Pacific, and then triggering the development of SST anomaly there.

   Can ENSO predict the switch between El Nino and La Nina?

   • For the past 30 years, ENSO forecasts have been limited to short lead times after ENSO sea surface temperature (SST) anomaly has already developed, but unable to predict the switch between El Nino and La Nina.

   Why is El Nino so important?

   • This environment supports more marine life and attracts more cold-water species, like squid and salmon, to places like the California coast. El Nino and La Nina are complex weather patterns resulting from variations in ocean temperatures in the Equatorial Pacific.

   • Indeed, the 1997 El Niño led to huge environmental disruptions, including wildfires in Indonesia that lasted into early 1998, the disappearance of marine life and decimation of the native bird population in the Galápagos Islands 9, marine heatwaves 10 and bleaching of corals 11.

   Feb 14, 2017 · El Niño events occur roughly every two to seven years, as the warm cycle alternates irregularly with its sibling La Niña—a cooling pattern in the eastern Pacific—and with neutral conditions. El Niño typically peaks between November and January, though the buildup can be spotted months in advance and its effects can take months to propagate around the world.
