Is 2020 an El Nino or El Nina year?
For the upcoming winter season, which extends from December 2021 through February 2022, there is an 87% chance of La Nina. Previous La Ninas occurred during the winter of 2020-2021 and 2017-2018, and an El Nino developed in 2018-2019.
Is ENSO just El Nino?
Though ENSO is a single climate phenomenon, it has three states, or phases, it can be in. The two opposite phases, “El Niño” and “La Niña,” require certain changes in both the ocean and the atmosphere because ENSO is a coupled climate phenomenon. “Neutral” is in the middle of the continuum.
What is the story of El Nino?
El Niño means Little Boy, or Christ Child in Spanish. South American fishermen first noticed periods of unusually warm water in the Pacific Ocean in the 1600s. The full name they used was El Niño de Navidad, because El Niño typically peaks around December.
When was the last time El Nino?
Since 2000, El Niño events have been observed in 2002–03, 2004–05, 2006–07, 2009–10, 2014–16, and 2018–19. Major ENSO events were recorded in the years 1790–93, 1828, 1876–78, 1891, 1925–26, 1972–73, 1982–83, 1997–98, and 2014–16.
Why is El Niño called El Niño?
Fishermen off the west coast of South America were the first to notice appearances of unusually warm water that occurred at year’s end. The phenomenon became known as El Niño because of its tendency to occur around Christmas time. El Niño is Spanish for “the boy child” and is named after the baby Jesus.
Are we in an El Niño or La Niña 2021?
La Niña continues as the Northern Hemisphere heads into winter, and forecasters are confident that it will hang around through the rest of the winter. This La Niña, the second in two years, will likely transition to ENSO-neutral sometime in the spring.
What is ENSO-neutral?
ENSO-neutral refers to those periods when neither El Ni o nor La Ni a is present. These periods often coincide with the transition between El Ni o and La Ni a events.
Is 2022 El Nio or La Niña?
PAGASA: La Niña is weakening and is likely to continue into the April-May-June 2022 season and then return to ENSO-neutral levels in May-Jun-Jul 2022. La Nina increases the likelihood of having above normal rainfall conditions in some areas of the country.
