What an El Niño is and clearly indicate where it occurs?
El niño is the development of warm waters. It occurs in the tropical pacific ocean.
What is El Niño La Nina apes?
4.9 El Niño and La Niña This occurs when the trade winds in that region weaken causing warm water to move closer to the west coast of South America and the thermocline to move deeper.
What is a consequence of El Niño conditions quizlet?
During El Nino what happens to the Walker Circulation: It weakens/ reverse causing the ocean surface to be warmer than average because less or no upwelling occurs in the eastern Pacific. During La Nina what happens to the Walker Circulation: It strengthens resulting in colder ocean temperatures due to more upwelling.
What are 3 effects of El Niño?
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.
What causes El Niño?
El Niño occurs when warm water builds up along the equator in the eastern Pacific. The warm ocean surface warms the atmosphere, which allows moisture-rich air to rise and develop into rainstorms. The clearest example of El Niño in this series of images is 1997.
What El Niño means?
El Niño means Little Boy, or Christ Child in Spanish. South American fishermen first noticed periods of unusually warm water in the Pacific Ocean in the 1600s. The full name they used was El Niño de Navidad, because El Niño typically peaks around December. El Niño can affect our weather significantly.
What El Niño Do?
El Niño is a weather pattern that occurs in the Pacific Ocean. During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. El Niño can cause more rain than usual in South and Central America and in the United States.
What does El Niño involve quizlet?
El Niño Conditions. Weak trade winds, pressure increases in the East & decreases in the West, strong counter current, warm water, An ENSO Event. The pressure over the East & West Pacific flip-flop → trade winds diminish → water moves east along the Equator → the surface waters of the East & Central Pacific warm.
What caused El Niño?
How El Niño affects climate?
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.
Why 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.
What happens during an El Niño event quizlet?
What happens during an El Nino event? During an El Niño event, warm water builds up in the equatorial Pacific, leading to severe weather events and impacts on marine life.
How does El Niño affect climate?
What is an El Niño quizlet?
El Nino. (oceanography) a warm ocean current that flows along the equator from the date line and south off the coast of Ecuador at Christmas time.
How El Niño develops?
What is a major El Niño event quizlet?
A condition where the central and eastern tropical Pacific Ocean turns cooler than normal is called. La Nina. During a major El Nino event. extensive ocean warming occurs over the tropical Pacific.
What causes El Niño quizlet?
is an abnormal weather pattern that is caused by the warming of the Pacific Ocean near the equator, off the coast of South America.
