The Pacific Decadal Oscillation is a long-lived pattern of North Pacific sea surface temperature variability that shifts between a warm phase, in which the interior of the North Pacific is cool and the coastal waters of North America are warm, and a cool phase with the opposite pattern. Unlike El Nino, whose phases last a year or two, the Pacific Decadal Oscillation phase can persist for twenty to thirty years at a stretch, and it was first named for its influence on Pacific salmon production cycles observed to track its shifts.
