what is called EL NINO ?

Question

I WANT TO KNOW THE REAL EXPLANATION ABOUT THIS WORD BECAUSE IT IS RELATED TO CLIMATOLOGY SUBJECT

Answer 1

El Niño-Southern Oscillation (ENSO) is a global coupled ocean-atmosphere phenomenon. The Pacific ocean signatures, El Niño and La Niña (also written in English as El Nino and La Nina) are major temperature fluctuations in surface waters of the tropical Eastern Pacific Ocean. The names, from the Spanish for "the child", refer to the Christ child, because the phenomenon is usually noticed around Christmas time in the Pacific Ocean off the west coast of South America.[1] Their effect on climate in the southern hemisphere is profound. These effects were first described in 1923 by Sir Gilbert Thomas Walker from whom the Walker circulation, an important aspect of the Pacific ENSO phenomenon, takes its name. The atmospheric signature, the Southern Oscillation (SO) reflects the monthly or seasonal fluctuations in the air pressure difference between Tahiti and Darwin. As of September 2006, El Niño is currently active, and is expected to continue into 2007.[2]

ENSO is a set of interacting parts of a single global system of coupled ocean-atmosphere climate fluctuations that come about as a consequence of oceanic and atmospheric circulation. ENSO is the most prominent known source of inter-annual variability in weather and climate around the world (~3 to 8 years), though not all areas are affected. ENSO has signatures in the Pacific, Atlantic and Indian Oceans.

In the Pacific, during major warm events El Niño warming extends over much of the tropical Pacific and becomes clearly linked to the SO intensity. While ENSO events are basically in phase between the Pacific and Indian Oceans, ENSO events in the Atlantic Ocean lag behind those in the Pacific by 12 to 18 months. Many of the countries most affected by ENSO events are developing countries within main continents (South America, Africa...), with economies that are largely dependent upon their agricultural and fishery sectors as a major source of food supply, employment, and foreign exchange. New capabilities to predict the onset of ENSO events in the three oceans can have global socio-economical impacts. While ENSO is a global and natural part of the Earth's climate, whether its intensity or frequency may change as a result of global warming is an important concern. Low-frequency variability has been evidenced. Inter-decadal modulation of ENSO might exist.

Answer 2

The name El Nino, meaning the Christ child, was given to a certain warm current that appeared each year off the coast of Peru at Christmas time. It was assumed that what we now call El Ninos were just unusually strong instances of the same event. Over time, El Nino has changed to mean only those irregular, strong events. It wasn't until the 1960's that scientists realized the far-reaching effects of this phenomena (1).

El Nino is only part of a larger phenomenon known as ENSO, or El Nino/Southern Oscillation. This large Oscillation deals with changes in the surface temperatures of the Eastern and Central parts of the equitorial Pacific Ocean. It causes variations in temperature of up to 4 degrees Celcius. This wide-spread oscillation was first recognized in 1923, when scientists noticed that the high pressure in the Pacific Ocean occurred simultaneously with low pressure in the Indian Ocean.



A warming of the ocean surface off the western coast of South America that occurs every 4 to 12 years when upwelling of cold, nutrient-rich water does not occur. It causes die-offs of plankton and fish and affects Pacific jet stream winds, altering storm tracks and creating unusual weather patterns in various parts of the world.

[American Spanish, from Spanish, the Christ child (from its onset being around Christmastide) : el, the (from Latin ille) + niño, child (from Old Spanish ninno, from Vulgar Latin *nīnnus).]

Answer 3

EL NINO usually happens in South America when the trade winds blowing to the east so then the current brings hot, moist winds which also create severe storms.

Answer 4

El Niño is an oscillation of the ocean-atmosphere system in the tropical Pacific having important consequences for weather around the globe.

Answer 5

in south america on the pacific ocean side, the fishermen discovered what they called "el nino" ( a warm current of water it think... not too sure) they named it el nino because it was christmas time and el nino means "the son" in spanish.

Answer 6

EL Niño is a weather climate which is in intense heat (drought). It usually occurs in countries which is near the equator. Its, contradictory situation is called La Niña, which produces continous heavy rain. ("EL" means boy, and "LA" means girl in Spanish.)

Answer 7

It's when the oceans waters warm
