The El Niño–Southern Oscillation is a single climate phenomenon that quasi-periodically fluctuates between three phases: Neutral, La Niña or El Niño. [12] La Niña and El Niño are opposite phases which require certain changes to take place in both the ocean and the atmosphere before an event is declared. [ 12 ]

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 ...
Indeed, the term El Niño–Southern Oscillation (ENSO) is an implicit acknowledgment that the phenomenon underlies variability in several locations at once. It was later noticed that associated teleconnections occurred all over North America, as embodied by the Pacific–North American teleconnection pattern .
El Niños and their opposites, La Niñas, are naturally occurring weather phenomena that usually appear every two to seven years as a function of how the Pacific Ocean interacts with the air above it.
The 2014–2016 El-Niño phenomenon, according to the World Meteorological Organization, is one of the three strongest since 1950. A number of countries in Africa including Lesotho , Swaziland and Zimbabwe declared national states of emergency, while the Southern African Development Community declared a regional drought disaster in March 2016.
