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
tropical-high latitude climate connection is limited prior to the
20(th)century. Herein tree-ring analysis is employed to extend understanding of
North Pacific climate variability and related tropical linkages over the past
four centuries. To this end, a tree-ring reconstruction of the December-May
North Pacific Index (NPI) - an index of the atmospheric circulation related to
the Aleutian Low Pressure Cell - is presented (1600-1983). The NPI
reconstruction shows evidence for the three regime shifts seen in the
instrumental NPI data, and for seven events in prior centuries. It correlates
significantly with both instrumental tropical climate indices and a coral-based
reconstruction of an optimal tropical Indo-Pacific climate index, supporting
evidence for a tropical/North Pacific link extending as far west as the western
Indian Ocean. The coral-based reconstruction (1781-1993) shows the 20(th)
century regime shifts evident in the instrumental NPI and instrumental tropical
Indo-Pacific climate index, and three previous shifts. Changes in the strength
of correlation between the reconstructions over time, and the different
identified shifts in both series prior to the 20(th) century suggest a varying
tropical influence on North Pacific climate, with greater influence in the
20(th) century. One likely mechanism is the low-frequency variability of the El
Nino-Southern Oscillation (ENSO) and its varying impact on Indo-Pacific
climate. CRN003, PI Dr. Brian Luckman.
