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 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 Niño patterns generally affect winters more than summers in the U.S. According to NOAA, a typical El Niño winter would produce a warmer, dryer winter season for most states in the mid ...
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 ...
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 ...
He and others (including Norwegian-American meteorologist Jacob Bjerknes) are generally credited with identifying the El Niño effect. [262] The major 1982–83 El Niño led to an upsurge of interest from the scientific community. The period 1990–95 was unusual in that El Niños have rarely occurred in such rapid succession.
After a year of dominance, El Niño's wrath has come to end — but it's climate-churning counterpart, La Niña, is hot on its heels and could signal a return to dryness for California.
El Nino Reshapes the Weather The third state is El Niño, which occurs when sea surface temperatures in the tropical Pacific rise to above-normal levels for an extended period of time.
