El Nino is a global climate anomaly. What does this mean?

"El Nino" is a Spanish transliteration, meaning "El Nino", "child prodigy" or "son of mind".

According to legend, long ago, ancient Indians living along the coast of Peru and Ecuador paid great attention to the relationship between the ocean and the weather. If the sea around Christmas is warmer than usual, it will rain heavily soon, accompanied by strange phenomena such as seabirds migrating in groups. Out of superstition, ancient Indians called this unusually warm trend "prodigy" trend, also known as "El Nino phenomenon", that is, "El Nino" trend.
