Vocabulary. El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Niño is the “warm phase” of a larger phenomenon called the El Niño-Southern Oscillation (ENSO). La Niña, the “cool phase” of ENSO, is a pattern that describes the unusual cooling of the region’s ...
Let us know. El Niño is a naturally occurring ocean-atmosphere climate pattern associated with warming of the ocean surface temperatures in the central and eastern tropical Pacific Ocean, which can significantly influence weather patterns, ocean conditions, and marine fisheries worldwide. El Niño occurs on average every two to s.
El Niño—the warm phase of the El Niño-Southern Oscillation ("ENSO") climate pattern—continues in the tropical Pacific, but the atmospheric part of the pattern is weakening. Conditions are likely to shift to ENSO-neutral by April-June 2024, and the odds of La Niña developing in June-August 2024 have risen to 55%. Latest Official ENSO Update.
El Nino and La Nina are climate patterns in the Pacific Ocean that can influence weather worldwide. Learn how they work, when they occur, and what impacts they have on weather, wildfires, ecosystems, and economies.
El Niño and La Niña are the warm and cool phases of ENSO (pronounced “en-so”). ENSO is the most influential natural climate pattern on Earth. ENSO swings back and forth every few years. El Niño and La Niña affect both the ocean and the atmosphere. Periods of weaker- or stronger-than-average easterly trade winds initiate El Niño and La ...
El Niño is part of the natural climate phenomenon called the El Niño Southern Oscillation (ENSO). It has two opposite states: El Niño and La Niña, both of which significantly alter global weather.
El Niño, Spanish for “little boy,” is a climate pattern that involves the unusual warming of surface waters in the eastern Pacific Ocean. As opposed to short-term weather events, climate events like El Niño are longer term environmental conditions that last months or even years. El Niño is the “warm phase” of a larger phenomenon ...
What Is El Niño? 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.
The entire pattern came to be known as ENSO, or El Niño-Southern Oscillation, and it includes the sister phenomenon known as La Niña. In April 2016, nearly 8,000 tons of sardines died and washed up along the coast of Chile, likely the result of El Niño related changes in the ocean.
El Niño conditions arose just a few months after its opposite pattern, La Niña, waned in the early months of 2023. “It was a quick transition,” says Emily Becker, a climate scientist at the ...
