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…

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 interdecadal

Interdecadal climate variability and regime‐scale shifts in Pacific North America

A transect of climate sensitive tree ring‐width chronologies from coastal western North America provides a useful proxy index of North Pacific ocean‐atmosphere variability since 1600 AD. Here we use

LETTERS North Pacific Decadal Climate Variability since 1661

Climate in the North Pacific and North American sectors has experienced interdecadal shifts during the twentieth century. A network of recently developed tree-ring chronologies for Southern and Baja

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,

Intensified decadal variability in tropical climate during the late 19th century

To evaluate and extend the record of decadal climate variability, we present a synthesis of 23 coral oxygen isotope records from the tropical Indo‐Pacific that extends back to A.D. 1850. Principal

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 catch

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 climate

Subtropical ocean ecosystem structure changes forced by North Pacific climate variations

Biological responses to basin-scale climate forcing in the subtropical North Pacific Ocean are assessed based on temporal variations in plankton community structure observed at Station ALOHA and

INTERDECADAL PACIFIC OSCILLATION AND SOUTH PACIFIC CLIMATE

The Interdecadal Pacific Oscillation (IPO) has been shown to be associated with decadal climate variability over parts of the Pacific Basin, and to modulate interannual El Niño–Southern Oscillation

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 the
