Detailed explanation-1: -Periods of weaker-or stronger-than-average easterly trade winds initiate El Niño and La Niña. By disrupting the atmospheric circulation in the planet’s largest ocean basin, El Niño shifts the average location and strength of the mid-latitude jet sreams, producing “side effects” on weather around the globe.
Detailed explanation-2: -The effects of El Niño in South America are direct and stronger than in North America. An El Niño is associated with warm and very wet weather months in April–October along the coasts of northern Peru and Ecuador, causing major flooding whenever the event is strong or extreme.
Detailed explanation-3: -The warm water sloshes back towards South America, which hides the nutrient-rich cold waters and ensures fish are in short supply. The lack of fish is the reason that El Nino was first discovered by the Peruvian fishermen. They noticed that every three to seven years, there would be virtually no fish in the seas.
Detailed explanation-4: -El Niño occurs when warm water builds up along the equator in the eastern Pacific. The warm ocean surface warms the atmosphere, which allows moisture-rich air to rise and develop into rainstorms.
