Is it La Niña or El Nino right now?
La Niña conditions are present. La Niña is favored to continue through the Northern Hemisphere winter 2021-22 (~95% chance) and transition to ENSO-neutral during the spring 2022 (~60% chance during April-June).
Is there a current El Nino?
As things stand with the El Niño-Southern Oscillation (ENSO), neutral conditions are currently present in the tropical Pacific and favored to last through the North American summer and into the fall. June 2021 sea surface temperature departure from the 1991-2020 average. …
How often does El Niño occur?
every 3 to 5 years
An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
When was the last El Niño year?
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.
How long is La Nina 2021?
The current La Niña is expected to persist until late summer or early autumn 2022. However, there are reasons to expect that this La Niña will not be as disruptive as the exceptionally strong event of 2010-12, including the fact that the 2010-12 La Niña coincided with a negative phase of the Indian Ocean Dipole.
When was the last El Nino event?
In general, El Niño events tend to only last for a single cycle (i.e. one year from autumn to autumn), but it is not uncommon for multi-year La Niña events to occur. For example, the 1998–2001 La Niña affected three consecutive years from autumn 1998 to autumn 2001.
How does El Nino effect the US?
Typically, in the United States, the most significant effect of El Nino is wetter weather and cooler-than-average temperatures across the southern portion of the country. The northern sector of the country usually experiences warmer weather and drier-than-average conditions. A dual effect is caused by El Nino.
Are We in an El Nino year?
GWO’s 2-year prediction discusses changes that will occur from July 2021 into July 2023 – including the next El Nino. For an El Niño to Form – the subsurface water must warm dramatically in the Western and Central Tropical Pacific – and then expand eastward across the Central Tropical Pacific and finally to near South America.
What is El Nino cycle?
El Nino Primer. El Nino is a state where the water temperatures in the Pacific Ocean near the equator become abnormally warm. This is a natural cycle that repeats itself on average about once every 2 to 7 years. El Ninos tend to begin in the summer and usually peak in intensity during the following winter.
