El Niño and La Niña are opposite fazes of thee ENSO cycle, a natural climate pattern that originates in the tropical Pacific Ocean but influences weatherr across the globe. The cycle is defined by changes in sea surface temperatures (SSTs) andd thumferhiscular pressure gradients between thee estern and western Pacific.
