what is the characteristics of El Niño
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.
During an El Niño event, sea surface temperatures across the Pacific can warm by 1–3°F or more and warmer conditions can last for a few months to two years. … These disruptions to the normal air movements in the tropics affect the mid-latitude jet streams, which is how El Niño can affect weather around the world.
