What does El Nino Southern Oscillation mean?
The El Niño-Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean.

Where does an El Nino Southern Oscillation occur?
The El Niño-Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean. On periods ranging from about three to seven years, the surface waters across a large swath of the tropical Pacific Ocean warm or cool by anywhere from 1°C to 3°C, compared ...
What causes El Nino event?
What causes an El Niño? An El Niño occurs when sea surface temperatures in the central and eastern tropical Pacific Ocean become substantially warmer than average, and this causes a shift in atmospheric circulation. Typically, the equatorial trade winds blow from east to west across the Pacific Ocean. El Niño events are associated with a weakening, or even reversal, of the prevailing trade ...
What is the El Niño Southern Oscillation quizlet?
-El Niño-Southern Oscillation (ENSO) is an irregularly periodical variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting much of the tropics and subtropics. -The warming phase is known as El Niño and the cooling phase as La Niña.
What happens during El Nino Southern Oscillation quizlet?
El Nino Southern Oscillation, trade winds weaken & warm surface water moves toward South America. Diminished fisheries off South America, drought in western Pacific, increased precipitation in southwestern North America, fewer Atlantic hurricanes.
What happens during El Nino Southern Oscillation?
The El Niño Southern Oscillation (ENSO) is a periodic shift of the ocean-atmosphere system in the tropical Pacific that impacts weather around the world. It happens every 3-7 years (5 years on average) and typically lasts nine months to two years. It is associated with floods, droughts, and other global disturbances.
What defines the Southern Oscillation quizlet?
Southern oscillation. the periodic change in the pressure differential between the Southeastern Pacific high pressure and the Western Pacific equatorial low pressure that occurs in concert with the El-Nino-Southern Oscillation events.
Why is the El Niño also called the Southern Oscillation?
The Southern Oscillation is a change in air pressure over the tropical Pacific Ocean. When coastal waters become warmer in the eastern tropical Pacific (El Niño), the atmospheric pressure above the ocean decreases. Climatologists define these linked phenomena as El Niño-Southern Oscillation (ENSO).
What is an El Niño event quizlet?
El Nino is a disruption of the ocean-atmospheric system, which is characterized by a large scale weakening of the trade winds and warming of the surface layers in the eastern and central equatorial Pacific Ocean.
What does Southern Oscillation mean?
The Southern Oscillation is an index based on the pressure difference between two tropical South Pacific locations, and is closely related to the El Niño state.
What is impacted the most when the El Nino Southern Oscillation cycle occurs?
El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
How El Niño occurs?
An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
Why is El Niño commonly referred to as El Nino Southern Oscillation ENSO )? Quizlet?
El Nino refers to the warm phase of the El Nino Southern Oscillation (ENSO), and involves a band of warm ocean water that develops in the East equatorial Pacific, affecting the tropics and sub-tropics. It is and irregular large-scale atmosphere-ocean phenomenon that is sometimes known as 'the heartbeat of the world'.
What causes El Niño La Niña?
El Niño and La Niña result from interaction between the surface of the ocean and the atmosphere in the tropical Pacific. Changes in the ocean impact the atmosphere and climate patterns around the globe. In turn, changes in the atmosphere impact the ocean temperatures and currents.
What are the global effects of El Niño?
During an El Niño event, sea surface temperatures across the Pacific can warm by 1–3°F or more for anything between a few months to two years. El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds.
What does Southern Oscillation mean?
The Southern Oscillation is an index based on the pressure difference between two tropical South Pacific locations, and is closely related to the El Niño state.

Why does the Eastern region have little precipitation?
Eastern region has little precipitation because of downward motion near the high pressure center.
Is El Nino global?
Since the effects of El Nino are global in nature, the costs can be astronomical.
