what is el nino class 9

El Nino is a climate pattern that describes the unusual warming of surface waters in the eastern equatorial Pacific Ocean. It is a large-scale ocean-atmosphere climatic interaction associated with a recurrent increase of sea surface temperatures in the central and east-central Pacific Ocean. El Nino can be understood as a natural phenomenon wherein the ocean temperatures rise especially in parts of the Pacific Ocean. It is the nomenclature which is referred to for a periodic development along the coast of Peru. This development is a temporary replacement of the cold current along the coast of Peru. The term El Nino basically means the child in Spanish. This is due to the fact that this current starts to flow around Christmas and hence the name referring to baby Christ. El Nino 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 surface waters. El Nino and La Nina are considered the ocean part of ENSO, while the Southern Oscillation is its atmospheric changes. El Nino can affect weather around the world, changing the odds of floods, drought, heat waves, and cold seasons for different regions, even raising global temperatures.
