El niño southern oscillation (enso) is a natural phenomenon that has occurred for centuries ocean and atmospheric conditions in the pacific tend to fluctuate between el niño (warming) and a drop in temperature in the tropical pacific known as la niña the fluctuations are rather irregular, but tend to appear every three.
