Strong El Niños have recently been observed from 1997 into 1998 and from 2015 into 2016. The increased chance for El Niño comes after La Niña conditions were present for nearly three straight ...
El Niño can significantly affect weather across the country, NOAA says. Warmer waters in the Pacific Ocean can alter jet streams and climate systems that help regulate temperatures, rainfall and ...
The relationship between El Niño and California rainfall has been described as "fragile", as only the "persistent El Niño" leads to consistently higher rainfall in the state, while the other flavors of ENSO have mixed effects at best. [14] Historically, El Niño was not understood to affect U.S. weather patterns until Christensen et al. (1981 ...
During an El Niño phase, the rising temperatures in the tropical Pacific can create significant changes in weather worldwide, including in the United States. The El Niño pattern has an impact on ...
El Niño is a natural climate event caused by the Southern Oscillation, popularly known as El Niño or also in meteorological circles as El Niño-Southern Oscillation or ENSO, [6] through which global warming of the eastern equatorial Pacific Ocean results in the development of unusually warm waters between the coast of South America and the ...
Originally, the term El Niño applied to an annual weak warm ocean current that ran southwards along the coast of Peru and Ecuador at about Christmas time. [16] However, over time the term has evolved and now refers to the warm and negative phase of the El Niño–Southern Oscillation (ENSO).
El Niño occurs when trade winds — the permanent east-to-west winds that blow near the Equator — weaken, allowing the Pacific Ocean’s warmer waters to push back east toward the United States ...
El Nino is a weather pattern associated with a disruption of wind patterns that means warmer ocean surface temperatures in the eastern and central Pacific. It can provoke extreme weather phenomena ...
