Where does El Niño come from?
El Niño was originally recognized by fisherman off the coast of South America as the appearance of unusually warm water in the Pacific Ocean, occurring near the beginning of the year. El Niño means The Little Boy or Christ child in Spanish.
Is El Niño man made?
El Niño events are actually just one half—the warm, wet half—of a naturally occurring weather cycle called the “El Niño-Southern Oscillation,” or ENSO.
What is El Niño easy explanation?
El Niño is an abnormal weather pattern caused by the warming of the Pacific Ocean near the equator, off the coast of South America. The sun warms the water near the equator, which can make more clouds and, therefore, more rain. Following an El Niño, an opposite phenomenon occurs, called La Niña.
How is La Niña different from El Niño?
El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas. These changes in the Pacific Ocean and its overlying atmosphere occur in a cycle known as the El Niño–Southern Oscillation (ENSO).
How can we prepare for El Niño and La Nina?
Preparation before the El Nino
- Storing some drinking water.
- Prepare some water pail/container in case of water rationing occur at your housing area.
- Figuring out the route to carry the distributed water to your home and the location of storage.
- Rain water harvesting system (if applicable)
- Face mask.
How are El Nino and La Nina weather patterns related?
El Niño and La Niña are complex weather patterns resulting from variations in ocean temperatures in the Equatorial Pacific. La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes,…
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). Today, most scientists use the terms El Niño and ENSO interchangeably.
How does El Nino affect the food production?
Food production is impacted by ENSO. Changes in ocean temperatures and currents that happen during El Niño impact marine life. This can impact individuals who make a living fishing and consumers who depend on certain fish for food.
What happens to the trade winds during an El Nino?
In an El Niño year, the trade winds weaken or break down. The warm water that is normally pushed towards the western Pacific washes back across, piling up on the east side of the Pacific from California to Chile, causing rain and storms.
