Earth's heat is mostly stored in the ocean. In the deep ocean, heat storage is consistent throughout decades to centuries, although surface temperatures vary seasonally and annually.
In El Niño events, Pacific sea surface temperatures can rise by 1–3°F or more, lasting from a few months to two years.
The extraordinary temperature is accompanied by a slowdown in the easterly trade winds, increased rainfall, and a dip in central tropical Pacific surface air pressure
El Niño disrupts tropical air patterns, affecting mid-latitude jet streams and global weather.

El Niño-influenced weather systems typically cause stronger cyclones in the North-Western Pacific and more frequent ones in the South Pacific.
El Niño is linked to extreme weather patterns globally. Some areas may get more rain, while others may not.
A greater El Niño increases the likelihood of its repercussions. While there is a correlation between El Niño strength and severity
