15 DECEMBER 2005 D’ARRIGO ET AL. 5253 Tropical–North Pacific Climate Linkages over the Past Four Centuries*
Analyses of instrumental data demonstrate robust linkages between decadal-scale North Pacific and tropical Indo-Pacific climatic variability. These linkages encompass common regime shifts, including the noteworthy 1976 transition in Pacific climate. However, information on Pacific decadal variabilit...
