El Niño–Southern Oscillation: History, Fundamentals & Impacts by region

El Niño–Southern Oscillation (ENSO) is a global climate phenomenon that emerges from variation in winds and sea surface temperatures over the tropical Pacific Ocean. Those variations have an irregular pattern but do have some appearance of cycles. The occurrence of ENSO is not easily predictable. It affects the climate of much of the tropics and…
