Evidence gleaned from the instrumental record of climate data identifies a robust, recurring pattern of ocean–atmosphere climate variability centered over the midlatitude North Pacific basin. Over the past century, the amplitude of this climate pattern has varied irregularly at interannual-to-interdecadal timescales. There is evidence of reversals in the prevailing polarity of the oscillation occurring around 1925, 1947, and 1977; the last two reversals correspond to dramatic shifts in salmon… Expand

The Pacific Decadal Oscillation and Pacific Salmon Production
Retrospective analyses of Pacific Basin climate records highlight the existence of a pan-Pacific interdecadal climate oscillation. We find strong evidence for coherent patterns of interdecadalExpand
Tropical pacific forcing of decadal SST variability in the western indian ocean over the past two centuries
TLDR
It is suggested that the tropical Pacific imparts substantial decadal climate variability to the western Indian Ocean and, by implication, may force decadal variability in other regions with strong El Nino-Southern Oscillation teleconnections. Expand

ENSO and interdecadal climate variability over the last century documented by geochemical records of two coral cores from the South West Pacific
Abstract. The south west Pacific is affected by climatic phenomena such as ENSO (El Nino Southern Oscillation) or the PDO (Pacific Decadal Oscillation). Near-monthly resolution calibrations of Sr/Ca,Expand
Inverse Production Regimes: Alaska and West Coast Pacific Salmon
Abstract A principal component analysis reveals that Pacific salmon catches in Alaska have varied inversely with catches from the U.S. West Coast during the past 70 years. If variations in catchExpand

Patterns of change in climate and Pacific salmon production
For much of the 20th century a clear north-south inverse production pattern for Pacific salmon had a time dynamic that closely followed that of the Pacific Decadal Oscillation (PDO), which is theExpand

The Pacific Decadal Oscillation
The Pacific Decadal Oscillation (PDO) has been described by some as a long-lived El Niño-like pattern of Pacific climate variability, and by others as a blend of two sometimes independent modesExpand
Pacific interdecadal variability in this century's sea surface temperatures
Analysis of this century's sea surface temperatures over the Pacific Ocean reveals an interdecadal oscillation with a period of 15–20 years. Our results show that the well-known 1976–77 climateExpand
