What years were El Nino years?
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.
Is 2011 an El Nino year?
Recent years when La Niña Modoki events occurred include 1973–1974, 1975–1976, 1983–1984, 1988–1989, 1998–1999, 2000–2001, 2008–2009, 2010–2011, and 2016–2017. The recent discovery of ENSO Modoki has some scientists believing it to be linked to global warming.
Is 2011 El Nino or La Nina?
The lead character in the 2011 climate story was La Niña—the cool phase of the El Niño-Southern Oscillation—which chilled the central and eastern tropical Pacific at both the start and the end of the year. The La Niña that was underway at the start of 2011 was among the strongest in the historical record.
When was the worst La Niña?
The 2010–11 La Niña was one of the strongest on record, comparable in strength to the events of 1917–18, 1955–56 and 1975–76.
What are the benefits of El Niño?
Some benefits of El Niño:
- Fewer hurricanes and other tropical cyclones in the north Atlantic.
- Milder winters in southern Canada and the northern continental United States.
- Replenishment of water supplies in the southwestern U.S.
- Less disease in some areas due to drier weather (like malaria in southeastern Africa)
What are the positive effects of La Niña?
La Niña usually has a positive impact on the fishing industry of western South America. Upwelling brings cold, nutrient-rich waters to the surface. Nutrients include plankton eaten by fish and crustaceans. Higher-level predators, including high-value fish species such as sea bass, prey on the crustaceans.
How often does El Nino and La Nina occur?
El Niño and La Niña are the warm and cool phases of a recurring climate pattern across the tropical Pacific—the El Niño-Southern Oscillation, or “ENSO” for short. The pattern can shift back and forth irregularly every two to seven years, and each phase triggers predictable disruptions of temperature, precipitation, and winds.
Where can I find El Nino weather data?
Global Climate Data & Maps – Climate, Weather Analyses and Weather Forecasts Graphic shows raltime global SST from Space Science and Engineering Center at the University of Wisconsin-Madison.
How does El Nino affect the Atlantic Ocean?
Even though El Niño occurs in the Pacific Ocean, it often reduces the number of hurricanes that form in the Atlantic Ocean. Conversely, La Niña events tend to be related to an increase in the number of Atlantic hurricanes. Food production is impacted by ENSO.
Is there going to be an El Nino in 2019?
The El Niño of 2019 is officially done. Neutral conditions have returned to the tropical Pacific, and of the three possible outcomes—El Niño, La Niña, or neutral—forecasters favor neutral to persist through Northern Hemisphere winter. More ENSO status information.
