2 de feb. de 2016 · El Niño is a naturally occurring 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 and La Niña are two opposing climate patterns that break these normal conditions. Scientists call these phenomena the El Niño-Southern Oscillation (ENSO) cycle. El Niño and La Niña can both have global impacts on weather, wildfires, ecosystems, and economies.
18 de ene. de 2016 · El Niño (the warm phase) and La Niña (the cool phase) lead to significant differences from the average ocean temperatures, winds, surface pressure, and rainfall across parts of the tropical Pacific. Neutral indicates that conditions are near their long-term average.
16 de oct. de 2023 · What is El Niño? 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.
Though ENSO is a single climate phenomenon, it has three phases - El Niño, La Niña and Neutral. El Niño, meaning “boy child” in Spanish, was first used some centuries ago by fishermen in Peru and Ecuador to refer to the unusually warm waters that reduced their catch just before Christmas.
