(El Niño -Southern Oscillation) is a composite term referring to the whole suite of events associated with these negative SOI episodes.
El Niño – Southern Oscillation El Niño Southern Oscillation Climatic phenomenon occurring in the Tropics that involves transports of warm (El Niño) or cold (La Niña) water masses from west to east across the Pacific basin. This displacement of water is accompanied by a shift of atmospheric cells, and therefore of winds and monsoons across the Tropics. This oscillation, which has been occurring at irregular intervals for thousands of years, has a global effect on climate. The phenomenon is named "El Niño" (meaning the Christ Child or the Little Boy in Spanish) because warm waters often reach the coast of Peru around Christmas time, often severely disrupting local fisheries.
a suite of events that occur at the time of an El Niño; at one extreme of the cycle, when the central Pacific Ocean is warm and the atmospheric pressure over Australia is relatively high, the ENSO causes drought conditions over eastern Australia ( see El Niño, SOI)
El Niño/Southern Oscillation: "The 1997-98 ENSO episode (not covered in this atlas) will go down in history in similar fashion to 1982-83".
iño/ outhern scillation. The condition in the tropical Pacific Ocean where the reversal of surface air pressure at opposite ends of the Pacific induces westerly winds, a strengthening in the equatorial countercurrent and extensive ocean surface warming.
Stands for El Niño–Southern Oscillation. ENSO refers to an irregular cycle of warming and cooling of the sea surface temperatures (see definition) of tropical Pacific Ocean. The cycle has a length of about 4 years, and is a natural part of the Earth's climate system. The oceanic warming and cooling is accompanied by changes in air pressure above the Pacific Ocean (the “Southern Oscillation”). These changes in the Pacific Ocean's temperatures and the atmosphere above it affect the global climate system, and therefore can affect the climate in regions that are far away from the Pacific (like Africa).
(El Niño/Southern Oscillation): A cyclical, large-scale changes in atmospheric and ocean patterns in which, among other things, warm surface water in the Pacific moves further to the east than normal. (see also El Niño)
acronym for El Niño/Southern Oscillation, it describes the simultaneous warming of the waters in the eastern Pacific and the shifting pattern of air pressure between the eastern and western edges of the Pacific Ocean.
Acronym for El Niño and Southern Oscillation to describe the linkage between the two phenomena.
Interacting parts of a single global system of climate fluctuations. ENSO is the most prominent known source of interannual variability in weather and climate around the world, though not all areas are affected. The Southern Oscillation (SO) is a global-scale seesaw in atmospheric pressure between Indonesia/North Australia, and the southeast Pacific. In major warm events El Niño warming extends over much of the tropical Pacific and becomes clearly linked to the SO pattern. Many of the countries most affected by ENSO events are developing countries 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 event can have a global impact. While ENSO is a natural part of the Earth's climate, whether its intensity or frequency may change as a result of global warming is an important concern.
(El Niño-Southern Oscillation) A term that connects the oceanic phenomenon (El Niño) with the atmospheric phenomenon (Southern Oscillation) leading to the realization of the global consequences of air-sea interaction (see TOGA).
An acronym for El Niño Southern Oscillation
El Niño/Southern Oscillation. ENSO is a general term used to describe both warm (El Niño) and cool (La Niña) ocean-atmosphere events in the tropical Pacific.
the disruption of the ocean-atmosphere system in the Pacific ocean and the impact that it has on weather around the globe
El Niño Southern Oscillation. the complex episodic sequence of events in the oceans and atmosphere
acronym for iño/ outhern scillation. ENSO is a general term used to describe both warm (El Niño) and cool (La Niña) ocean-atmosphere events in the tropical Pacific as well as the Southern Oscillation the atmospheric component of these phenomena.
The El Niño-Southern Oscillation is a semi-regular climatic phenomenon involving regional interactions between the ocean and the atmosphere.
El Nino Southern Oscillation. El Nino, in its original sense, is a warmwater current that periodically flows along the coast of Ecuador and Peru, disrupting the local fishery. This oceanic event is associated with a fluctuation of the intertropical surface pressure pattern and circulation in the Indian and Pacific Oceans, called the Southern Oscillation. This coupled atmosphere-ocean phenomenon is collectively known as El Nino Southern Oscillation, or ENSO. During an El Nino event, the prevailing trade winds weaken and the equatorial countercurrent strengthens, causing warm surface waters in the Indonesian area to flow eastward to overlie the cold waters of the Peru current. This event has great impact on the wind, sea surface temperature, and precipitation patterns in the tropical Pacific. It has climatic effects throughout the Pacific region and in many other parts of the world. The opposite of an El Nino event is called La NiÒa.
Abbreviation for El Niño-Southern Oscillation, a reference to the state of the Southern Oscillation.
El Niño Southern Oscillation. The term currently used by scientists to describe basin-wide changes every 2 to 7 years in air-sea interaction in the equatorial Pacific Ocean. El Niño/La Niña is the oceanic component and the Southern Oscillation is the atmospheric component of the phenomenon.
See El Niño-Southern Oscillation.
El Niño Southern Oscillation. This refers to a complex of climatic anomalies whereby warm surface waters mask the usual increase in cold-water nutrient-rich ( upwellings) along the oceanic coasts of Peru and Ecuador. This phenomenon occurs around Christmas time (El Niño for the "Christ Child" in Spanish), with adverse effects on fishing activities, and is more severe some years and associated with catastrophic seasonal flooding along the normally arid coast. The expression El Niño now indicates these exceptional years (referred to as ENSO years, e.g.1982-1983) which occur at irregular intervals (2- to 10 years) and are accompanied by significant changes in the oceanic circulation, wind conditions throughout the tropical Pacific region, with a consequent impact on weather patterns around the world.
El Niño Southern Oscillation. Term coined in the early 1980s in recognition of the intimate linkage between El Niño events and the Southern Oscillation, which, prior to the late 1960s, had been viewed as two unrelated phenomena. The interactive global ocean-atmosphere cycle comprising El Niño and La Niña is often called the ENSO cycle.
El Nino Southern Oscillation. n: Flip-flopping pressure systems in the South Pacific that trigger short-lived global changes in climate. Warm waters from the western Pacific move across the ocean, just below the equator, and significantly warm the eastern tropical Pacific.
