What is the difference between El Nino and La Nina weather?
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific. It represents the cold phase of the ENSO cycle.
What is the difference between El Niño and climate change?
Is El Niño caused by climate change? No. El Niño events are not caused by climate change – they are a natural reoccurring phenomenon that have been occurring for thousands of years.
How does the climate change affect the ocean during El Niño?
In a warming climate, rainfall extremes are projected to shift eastward along the equator in the Pacific Ocean during El Niño events and westward during extreme La Niña events.
What are some differences between El Niño and La Nina quizlet?
El Nino is the condition in which the waters in the tropical central and eastern Pacific Ocean are warmer than average, while La Nina is the opposite, where those waters are colder than average. These differences seem to affect the weather pattern over the Pacific and surrounding areas.
What weather differences and other phenomena occur during a La Nina?
This warm pool expands to cover the tropics during El Niño, but during La Niña, the easterly trade winds strengthen and cold upwelling along the equator and the West coast of South America intensifies. Sea-surface temperatures along the equator can fall as much as 7 degrees F below normal.
What is the difference between climate change mitigation and adaptation?
In essence, adaptation can be understood as the process of adjusting to the current and future effects of climate change. Mitigation means making the impacts of climate change less severe by preventing or reducing the emission of greenhouse gases (GHG) into the atmosphere.
How does El Niño relate to climate change?
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 weather differences and other phenomena occur during a La Niña?
How does La Niña affect climate?
How La Niña may impact winter weather in the U.S. The climate pattern known as La Niña generally brings winters that are drier and warmer than usual across the southern U.S. and cooler and wetter in the northern part of the country.
How do El Nino and La Nina affect climate quizlet?
What are the weather conditions during El Niño? Sea surface temperatures are warmer, which increases evaporation which causes an increase in precipitation. Ocean water near the equator shifts between warmer than average (el Nino) and colder than average (la Niña) conditions.
