What are el niño, la niña, and enso near the end of each calendar year, ocean surface temperatures warm along the coasts of ecuador and northern peru in the past, local residents referred to this annual warming as “el niño,” meaning “the child,” southern oscillation the term el niño now refers to the coupled ocean-atmosphere.

An introduction to el nino or el nino southern oscillation or enso

El niño and la niña are the oceanic components, while the southern oscillation is the atmospheric counterpart, thus giving rise to the term ‘el niño/southern oscillation’ (enso) enso occurs in irregular cycles of two to seven years, and presents three phases: el niño, la niña and a neutral phase. El niño and la niña are opposite phases of what is known as the el niño-southern oscillation (enso) cycle the enso cycle is a scientific term that describes the fluctuations in temperature between the ocean and atmosphere in the east-central equatorial pacific (approximately between the international date line and 120 degrees west. El niño/southern oscillation (enso) remains the most important coupled ocean–atmosphere phenomenon to cause global climate variability on seasonal to interannual time scales this paper addresses the need for a reliable enso index that allows for the historical definition of enso events in the instrumental record back to 1871.
