Detailed explanation-1: -The term El Nino refers to the coupled ocean-atmosphere phenomenon characterized by: Abnormally warm sea surface temperatures from the date line (180W) east to the South American coast. Changes in the distribution of tropical rainfall from the eastern Indian Ocean east to the tropical Atlantic.
Detailed explanation-2: -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.
Detailed explanation-3: -The term El Niño originally described a weak warming of the ocean water that ran southward along the coast of Peru and Ecuador about Christmastime each year and resulted in poor fishing. Today, El Niño refers to a large-scale disturbance of the ocean and atmosphere in the tropical Pacific.
Detailed explanation-4: -La Niña is a climate pattern that describes the cooling of surface-ocean waters along the tropical west coast of South America. La Niña is considered to be the counterpart to El Niño, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean.
