Authors: Rosanne DArrigo(1), Rob Wilson(2), Clara Deser(3), Gregory Wiles(4), Edward Cook(1), Ricardo Villalba(5) , Alexander Tudhope(2), Julia Cole(6) and Braddock Linsley(7) (1)Tree-Ring Laboratory, Lamont-Doherty Earth Observatory, Palisades, NY 10964 USA (2)School of GeoSciences, Grant Institute, Edinburgh University, Edinburgh, United Kingdom (3)NCAR, Boulder, CO (4)The College of Wooster, Wooster, Ohio (5)IANIGLA, Mendoza, Argentina (6)Dept. of Geosciences University of Arizona, Tucson AZ (7)Program in Geological Sciences, Department of Earth and Atmospheric Sciences University at Albany, Albany, NY 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. |
