When do we go into El Nino?
October 14, 2021. La Niña —the cool phase of the El Niño-Southern Oscillation climate pattern—kept a firm grip on the tropical Pacific in January 2022, and there's 77% chance it will persist through May. Scroll down to learn more about typical U.S. impacts of La Niña. Latest Official ENSO Update.
What unusual pattern occurs during El Nino?
The Short Answer: El Niño is a weather pattern that occurs in the Pacific Ocean. During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. El Niño can cause more rain than usual in South and Central America and in the United States. El Niño is a weather pattern that occurs in the Pacific Ocean, but it is so big that it affects weather all over the world.
What is the current status of El Nino?
Current climate state: ENSO phase is currently neutral or declining La Niña. SOI analogues: Of the 10 years that most closely resemble the current SOI pattern, 4 or more have shown El Niño characteristics. Sub-surface: Significant sub-surface warming has been observed in the western or central equatorial Pacific Ocean.
What are some facts about El Nino?
El Niño Facts. El Nino is a climate pattern that causes extreme weather conditions. El Nino occurs when there is large-scale warming of the surface of the Pacific Ocean, which can cause droughts, floods and even fishing and agriculture issues as its warm waters move east. El Nino lasts for anywhere from nine months to two years, and it occurs ...

Are we in a El Nino 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 La Niña 2022?
The third straight winter of La Niña expected for 2022-2023. This winter we are expecting a La Niña Phase in the Pacific Ocean. The could mean we see a wetter than normal winter, but does that mean it will be a snowier than normal winter as well? By: Brandon Spinner. Posted at 5:14 PM, Aug 16, 2022.
Is 2023 an El Nino year?
"While a majority of NMME models suggest that La Niña will transition to ENSO-neutral in January-March 2023, forecasters are split on this outcome resulting in equal forecast probabilities for that season," the National Weather Service's Climate Prediction Center said.
Is 2022 going to be a hot summer?
The summer of 2022 is shaping up to be a scorcher. June 2022 saw the warmest temperatures on record over the world's land areas – and record–breaking heatwaves have swept across the northern hemisphere, particularly continental Europe, the UK, China and parts of the US.

What's the difference between El Niño and La Niña?
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
When was the last El Niño?
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.
What is El Nino?
Near the end of each calendar year, ocean surface temperatures warm along the coasts of Ecuador and northern Peru. In the past, local residents referred to this annual warming as “El Nino,” meaning “The Child,” due to its appearance around the Christmas season. The appearance of El Nino signified the end of the fishing season and the arrival of the time for Peruvian fishermen to repair their nets and maintain their boats. Every two to seven years a much stronger warming appears along the west coast of South America, lasting for several months and often accompanied by heavy rainfall in the arid coastal regions of Ecuador and northern Peru. Over time the term El Nino began to be used in reference to these major warm episodes. During the 1960s, scientists began to link the abnormally warm waters along the west coast of South America with abnormally warm waters throughout the central and east-central equatorial Pacific. In addition, the warmer than average waters were shown to be closely related to a global atmospheric pressure oscillation known as the Southern Oscillation. The term El Nino refers to the coupled ocean-atmosphere phenomenon characterized by: 1 Abnormally warm sea surface temperatures from the date line (180W) east to the South American coast 2 Changes in the distribution of tropical rainfall from the eastern Indian Ocean east to the tropical Atlantic 3 Changes in sea level pressure throughout the global Tropics 4 Large-scale atmospheric circulation changes in the Tropics and portions of the extra-tropics in both hemispheres
What is the El Nino phenomenon?
Other terms commonly used for the El Nino phenomenon include “Pacific warm episode” and “El Nino/ Southern Oscillation (ENSO) episode.” The El Nino phenomena and its counterpart, La Nina (where tropical Pacific water is cooler than normal) are the main sources of year-to-year variability in weather and climate for many areas of the world. El Nino and La Nina tend to alternate in an irregular cycle, which is often referred to as the ENSO cycle. El Nino episodes tend to:
What is the cycle of El Nino?
El Nino and La Nina tend to alternate in an irregular cycle, which is often referred to as the ENSO cycle . El Nino episodes tend to: There is considerable event-to-event variability in the timing, intensity and evolution of both El Nino and La Nina.
How long does El Nino last?
Every two to seven years a much stronger warming appears along the west coast of South America, lasting for several months and often accompanied by heavy rainfall in the arid coastal regions of Ecuador and northern Peru. Over time the term El Nino began to be used in reference to these major warm episodes.
Where does El Nino occur?

Is El Nino or La Nina enso neutral?
There is considerable event-to-event variability in the timing, intensity and evolution of both El Nino and La Nina. Periods when neither El Nino nor La Nina is present are referred to as ENSO-neutral.
Is El Nino lower than La Nina?
As we can see from the plots, winter precipitation during El Nino events tends to be slightly lower than ENSO-neutral or La Nina. Temperatures are more variable for El Nino than ENSO-neutral or La Nina, with no significant change in median value. These are the conclusions we can have confidence in, based on the historical record.
What are the winter impacts of ENSO neutral events?
Typical winter impacts associated with ENSO neutral events. Colder probabilities are favored across north-central and northeast portions of the US, due to a polar jet stream shifted further south. Meanwhile, warmer probabilities are favored across ths southern US, with above normal precipitation favored across portions of the southeast US. Image courtesy of Ray Wolf, National Weather Serivce.
Why is ENSO important?
ENSO is one of the most important climate phenomena on Earth due to its ability to change the global atmospheric circulation, which in turn, influences temperature and precipitation across the globe.
What is the enso cycle?
This oscillating warming and cooling pattern , referred to as the ENSO cycle, directly affects rainfall distribution in the tropics and can have a strong influence on weather across the United States and other parts of the world. El Niño and La Niña are the extreme phases of the ENSO cycle; between these two phases is a third phase called ENSO-neutral.
Is Kansas cooler than normal?
Slightly cooler than normal temperatures are favored over northwest Kansas during summer, with near normal temperatures elsewhere. Meanwhile, near to slightly above normal precipitation is favored across much of the state during winter and over northwest Kansas during summer, with near normal precipitation elsewhere.
How much of the time an ENSO event occurred?
About 70% of the time an ALERT was reached, an ENSO event subsequently occurred.
Who makes ENSO alerts?
The final decision to declare an ENSO Outlook status level (e.g., El Niño ALERT) is made by climatologists at the Bureau of Meteorology . As expert analysis by climatologists is not available for past assessments, the verification is based on the set criteria alone.
What happens to an ENSO status?
Once an ENSO Outlook status level is reached, it remains valid until it is either increased to the next level or cancelled, or if an ENSO event has been declared, the event officially declared over. This is done by climatologists at the Bureau of Meteorology.
What is the purpose of the Enso Outlook?
The purpose of the ENSO Outlook is to look ahead and assess the likely evolution of the El Nino-Southern Oscillation as it transitions through the different phases of ENSO (El Niño, La Niña and Neutral ). It aims to forewarn the Australian community using a staged approach based on changes in the likelihood or risk of an El Niño or La Niña occurring.
How is the status of ENSO Outlook determined?
The status of the ENSO Outlook is determined using set criteria (described below) and expert analysis by climatologists at the Bureau of Meteorology. It is updated fortnightly.
When does ENSO Outlook show the status of an event?
The ENSO Outlook will display the developing event status from March, even if there is an event still active.
When is Enso Outlook updated?
The ENSO Outlook status is updated each fortnight. The below graph shows the fortnightly values dating back to January 1980. The below table shows the monthly value of the ENSO Outlook for historical comparisons. The ENSO Outlook graph and table are not an official time-line of ENSO events. For the official history of El Niño and La Niña events see:
What is the term for the oceanic nino index?
Today, most scientists use the terms El Niño and ENSO interchangeably. Scientists use the Oceanic Nino Index (ONI) to measure deviations from normal sea surface temperatures. El Niño events are indicated by sea surface temperature increases of more than 0.9° Fahrenheit for at least five successive three-month seasons.
What is the cool phase of ENSO?
La Nina, the “cool phase” of ENSO, is a pattern that describes the unusual cooling of the region’s surface waters. El Niño and La Niña are considered the ocean part of ENSO, while the Southern Oscillation is its atmospheric changes.
What is upwelling in Peru?
Upwelling provides food for a wide variety of marine life, including most major fisheries. Fishing is one of the primary industries of Peru, Ecuador, and Chile. Some of the fisheries include anchovy, sardine, mackerel, shrimp, tuna, and hake. The upwelling process also influences global climate.
