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. The low-level surface winds, which normally blow from east to west along the equator (“easterly winds”), instead weaken or, in some cases, start blowing the other direction (from west to east …
Feb 26, 1998 · An El Niño (EN) occurs when unusually warm water appears at the surface in the central and eastern Pacific Ocean near the equator. The term El Niño, is Spanish for "the Christ Child." It was originally used by Peruvian fisherman to describe the annual appearance of warm water along their western coast around Christmas time each year.
El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern equatorial Pacific Ocean. El Niño has an impact on ocean temperatures, the speed and strength of ocean currents, the health of coastal fisheries, and local weather from Australia to South America and beyond. ...Oct 30, 2015
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases. ...Apr 26, 2016
The Short Answer: El Niño is a weather pattern that occurs in the Pacific Ocean. During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. El Niño can cause more rain than usual in South and Central America and in the United States.
El Nino. (oceanography) a warm ocean current that flows along the equator from the date line and south off the coast of Ecuador at Christmas time. La Nina. A cooling of the ocean surface off the western coast of South America, occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.
In Africa, El Niño conditions are associated with increased rainfall in East Africa and decreased rainfall in southern Africa, West Africa, and parts of the Sahel.Apr 10, 2017
The El Nino effect refers to uneven climatic changes due to rise in temperature. It leads to increased melting of polar ice caps as well as other places like the Himalayan snow caps. This results in the rise in the sea level which can submerge many coastal areas, thus resulting in biodiversity loss.May 29, 2020

El Nino refers to the large-scale ocean-atmosphere climate interaction linked to periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. It is associated with high pressure in the western Pacific. El Nino adversely impacts the Indian monsoons and hence, agriculture in India.
(i) The presence of the EL-Nino leads to an increase in sea-surface temperatures. (ii) It weakens the trade winds in the regions and causes heavy rainfall, floods or droughts in different regions of the world.Dec 28, 2017
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.Jun 4, 2021
El Niño conditions suppress the development of tropical storms and hurricanes in the tropical Atlantic and Caribbean due to the increased strength of the high level winds blowing from west to east in tropical latitudes; La Niña (cold conditions in the equatorial Pacific) favor hurricane formation in the tropical ...
During El Nino however, the pressure changes causing trade winds to diminish and warm water to move eastward instead of westward along the equator. This causes the traditionally cold waters along the coast of west South America to become warmer.
