Tropical-North Pacific Climate Linkages Over the Past Four Centuries
Instrumental analyses demonstrate robust linkages between decadal-scale North Pacific and tropical Indo-Pacific climate variability. These linkages encompass common regime shifts, including the noteworthy 1976 transition in Pacific climate. However, information on Pacific Decadal Variability and the...
