What is EI Nino what is its effects?
The term El Niño (Spanish for ‘the Christ Child’) refers to a warming of the ocean surface (or above-average sea surface temperatures) in the central and eastern tropical Pacific Ocean. El Niño events can disrupt normal weather patterns in the United States and globally. …
What are the effects of El Nino on the environment?
During El Niño, the warm waters from the western tropical Pacific migrate eastward as the trade winds weaken….
| Condition: | Effect: |
|---|---|
| droughts | crop failure increase in disease due to lack of water for sanitation and hygiene blowing dust pollution of viable water sources decrease in near-shore coastal water quality |
What happens due to coral reef damage by El Nino?
What happens due to coral reef damage by El Niño? a. The ocean water gets warmer. Fish that depend on the reef die.
What are the effects of El Niño 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.
Which of these is commonly an effect of El Niño?
El Niño also produces widespread and sometimes severe changes in the climate. Convection above warmer surface waters bring increased precipitation. Rainfall increases drastically in Ecuador and northern Peru, contributing to coastal flooding and erosion.
Which is associated with El Niño?
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.
What is the meaning of El Niño?
El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Nino is the “warm phase” of a larger phenomenon called the El Nino-Southern Oscillation (ENSO).
Where does El Niño occur?
Pacific Ocean
How long does El Niño last?
9-12 months
How often does El Niño occur?
approximately every two to seven years
What season does El Nino occur?
Over North America, the main temperature and precipitation impacts of El Niño, generally occur in the six months between October and March.
What is the difference between El Niño and La Niña?
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
What are common characteristics of El Niño and La Niña?
El Niño is characterized by a positive ONI greater than or equal to +0.5°C. La Niña is characterized by a negative ONI less than or equal to -0.5°C. Whenever the ONI is between +0.5 and -0.5, conditions are referred to as ENSO-neutral.
What are the causes of La Nina?
La Niña is caused by a build-up of cooler-than-normal waters in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn. Unusually strong, eastward-moving trade winds and ocean currents bring this cold water to the surface, a process known as upwelling.
