EL-NINO EFFECT details
El Nino is not a storm but rather a weather phenomenon in the Pacific Ocean during an El Nino the surface water temperature warms up leading to complex weather patterns Southern American fishers in the 19th-century painting warmer waters during Wintertime minted the name, El Nino
Spanish for the Blessed child nowadays when sea surface temperatures in the equatorial Pacific Ocean rise point 5 degrees Celsius over their historic average for three consecutive months and once atmospheric conditions and rainfall patterns shift accordingly scientists officially declare an El Nino an El Nino event takes place about every two to seven years normal east to west trade winds over the Pacific weaken and warm water that normally travels westward is now moving toward the east moisture then rises into the air and the effects of El Nino are felt throughout the Americas in the ocean warm water pushes colder water downward blocking the important upwelling of nutrient-rich waters from the bottom this causes some marine life to migrate to colder waters animals that normally feed on the sea life suffer and Fisheries throughout Central and South America suffer too but El Ninos most noticeable repercussions are felt on land in the western United States and Central and South America the warm air and moisture lead to increased storms rainfall floods loss of life and property and the increase of some vector-borne diseases like malaria even in places.
EL-NINO EFFECT – It’s Meaning And Details
where they don’t normally occur in Southeast Asia and Australia the opposite takes place there was record flooding in Peru and u.s. saw storms in the Gulf Coast flash flooding from California to Mississippi and tornadoes in Florida scientists are now better able to predict if and when an El Nino event will take place this helps communities better prepare for the changes in weather patterns and better adapt to its repercussions.

Every year at Christmas time, a warm equatorial current flows south along the Peruvian coast. In the 19th century, a Peruvian fisherman named that annual present “El Niño” in honor of the child of Christ (El Niño means “child” in Spanish). Later, when scientists mentioned that this hot flow was more intense than normal in a few years, they adopted the name and applied it to that more powerful but uncertain climatic event. Now El Niño is used almost exclusively for serious episodes rather than annual ones to which it was originally applied.
El Niño has an impact on sea heat, the speed, and strength of ocean tides, the health of the marginal fish trap, and the calm from Australia to South America and away. The incidence of El Nino occurs irregularly at intervals of two to seven years. However, El Niño is not a regular cycle or conjecture in the sense that the oceans are tides.
El Niño was identified by fishermen off the Peruvian coast as the presence of unusually warm waters. We have no real record of what the indigenous Peruvian people called the incident, but Spanish immigrants call it El Niño, which means “little boy” in Spanish. When capitalized, El Niño means Christ Child and was used because the event often came around Christmas. El Niño soon came to describe irregular and rapid climatic changes rather than the warming of coastal surface waters.
In the 1930s, led by the work of Sir Gilbert Walker, climatologists determined that El Niño coincided with southern oscillations. The southern uncertainty is a difference in air pressure over the tropical Pacific Ocean. When the coastal waters in the eastern tropical Pacific region (El Niño) heat up, the atmospheric pressure over the ocean decreases. Climatologists define these linked events like El Niño – Southern Oscillations (ENSO). Today, most scientists interchange El Niño and ENSO.
Scientists use the Oceanic Niño Index (ONI) to measure deviations from normal sea surface temperatures. Incidents of El Niño indicate sea surface temperatures exceeding 0.9 ° F for at least five consecutive three-month seasons. The intensity of El Niño events varies from weak temperature rise (about 4–5 ° F), with only moderate local effects on climate and very strong growth (14–18 ° F) on climate change associated with climate change worldwide. it occurs.
