What climate conditions occur during El Niño?
During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.
What climate changes does the El Niño cause?
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 type of conditions does El Niño and La Niña come from?
When sea-surface temperatures are above average by about 1 degree Fahrenheit or more, El Niño can develop. When temperatures are below average, La Niña can form. When temperatures are at or near average — what’s called ENSO-neutral — neither develops.
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. These winds pile up warm surface water in the west Pacific so that the sea surface is about one-half meter higher around Indonesia than around Ecuador.
Which condition happens during La Niña phenomenon?
La Niña is a weather phenomena characterized by unusually cold ocean temperature in the Equatorial Pacific which causes increased numbers of tropical storms in the Pacific Ocean. Disease related to contaminated water due to flooding, such as acute gastroenteritis, typhoid fever, cholera and hepatitis A.
What are the environmental impacts of El Niño?
| Condition: | Effect: |
|---|---|
| higher sea levels | salt water intrusion into water supplies coastal erosion and damage to shoreline and property |
| flooding/increased rainfall | contamination of drinking water systems flooding of wastewater systems contamination of recreational sites and estuaries waterborne illness |
Is El Niño climate or weather?
El Niño and La Niña are climate patterns in the Pacific Ocean that can affect weather worldwide. During normal conditions in the Pacific ocean, trade winds blow west along the equator, taking warm water from South America towards Asia.
How does El Nino and La Nina affect climate?
During El Niño, surface water in the central and eastern equatorial Pacific Ocean is unusually warm. La Niña usually impacts U.S. weather by bringing cooler weather to the northwest and warmer weather to the southeast, though just like El Niño, not every La Niña event affects U.S. weather identically.
What climate conditions occur during La Niña?
During a La Niña year, winter temperatures are warmer than normal in the South and cooler than normal in the North. La Niña can also lead to a more severe hurricane season. La Niña causes the jet stream to move northward and to weaken over the eastern Pacific.
What is El Nina weather?
La Niña (translated from Spanish as “little girl”) is not a storm, but a climate pattern that occurs in the Pacific Ocean every few years and can impact weather around the world.
What is ENSO climate?
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. El Niño and La Niña are the extreme phases of the ENSO cycle; between these two phases is a third phase called ENSO-neutral.
