“…The PDO climate pattern was described by Zhang et al (1997) and Mantua et al (1997). Many authors have reported strong relationships between the Pacific climate features and climate, hydrology and ecology (Knox and Lawford, 1990;Francis and Hare, 1994;Francis et al, 1998;Bonsal and Lawford, 1999;Hare et al, 1999;Overland et al, 1999;Dettinger and Diaz, 2000;Bond and Harrison, 2000;Brito-Castillo et al, 2003;Pavia et al, 2006). The PDO index as developed by Hare (1996) and Zhang (1996), and used by Mantua et al (1997), is the leading principal component (PC) from an un-rotated empirical orthogonal function analysis (EOFA) of monthly "residual" sea surface temperature anomalies, poleward of 20°N for the 1900-1993 period of record.…”

Abstract:The Pacific Decadal Oscillation (PDO) is a large-scale climate system feature that influences the surface climate and hydrology of western North America. In this paper, we review the literature describing the PDO and demonstrate its effects on temperature, precipitation, snowfall, glacier mass balance, and streamflow with a focus on western Canada, and particularly British Columbia. We review how the PDO index was developed and discuss other North Pacific climate patterns that resemble the PDO. The impacts of PDO on glacier mass balance and streamflow from retrospective studies are also reviewed and illustrated with specific examples from BC. We assess the current state of knowledge regarding the PDO and provide a critical assessment of its use in hydroclimatology. This information should provide insight on the sensitivity of projects to climatic variability.

“…Trees that were not significantly correlated with the mean chronology (decay or multiple pieces cause) were excluded. Prior to the analysis, ring width series were generally standardized with the program ARSTAN (Cook and Holmes, 1986). The aim of the procedure, called detrending, is to remove non-climatic variation such as a hypothesized negative exponential age-related trend by fitting a curve to each tree ring series.…”

“…This is to say tree growth rings represent records of chronological series which are witnesses of the environment and climate that influenced their growth in the past (Fritts, 1976;Hughes et al, 1982;Wu et al, 1990), and it became necessary to indirectly monitor solar variations and other geophysical phenomena at a relatively long time scale into the past. The study of relations between tree rings and Sun-Earth climatic factors is becoming a common scientific task (Fritts, 1976;Hughes et al, 1982;Wu et al, 1990;Mann et al, 1998Mann et al, , 1999Barber et al, 2000;Crowley, 2000;Rind, 2002;Briffa et al, 1998Briffa et al, , 2004Briffa and Osborn, 2002;Cook et al, 2004;Esper et al, 2002;D'Arrigo et al, 2005;IPCC, 2001;Zhou and Butler, 1998;Brito-Castillo et al, 2003). Most of these investigations based on the trees that are located in undisturbed regions and far away from human habitation.…”

“…Long reconstructions can be developed by correlating tree-growth records with discharge in unregulated rivers (natural flow) and the characteristic variability analyzed at several frequencies. Reconstructions of streamflow from tree rings have been extensively used in North America to document and understand long term trends in surface water availability (e.g., Meko et al 1995;Stockton and Jacoby 1976;Hidalgo et al 2000;Pederson et al 2001;Woodhouse 2001;Jain et al 2002;Brito-Castillo et al 2003).…”

A 400-year tree-ring record of the Puelo River summer–fall streamflow in the Valdivian Rainforest eco-region, Chile

The Puelo River is a watershed shared between Chile and Argentina with a mean annual streamflow of 644 m 3 s −1 . It has a high ecologic and economic importance, including introduced farmed salmon, tourism, sports fishing and projected hydroelectricity. Using Austrocedrus chilensis and Pilgerodendron uviferum tree-ring records we reconstructed summer-fall (December-May) Puelo River streamflow, which is the first of such reconstructions developed in the Pacific domain of South America. The reconstruction goes back to 1599 and has an adjusted r 2 of 0.42. Spectral analysis of the reconstructed streamflow shows a dominant 84-year cycle which explains 25.1% of the total temporal variability. The Puelo River summer-fall streamflow shows a significant correlation (P>0.95, 1943-2002) with hydrological records throughout a vast geographic range within the Valdivian eco-region (35 to 46°S). Seasonal Puelo River interannual streamflow variability is related to large-scale oceanic and atmospheric circulation features. Summer-fall streamflows showed a significant negative correlation with the Antarctic Oscillation (AAO), whereas winter-spring anomalies appear to be positively connected with sea surface temperature variations in the tropical Pacific. In general, above-and below-average discharges in winterspring are related to El Niño and La Niña events, respectively. The temporal patterns of the observed and reconstructed records of the Puelo River streamflow show a general decreasing trend in the 1943-1999 period. Projected circulation changes for the next decades in the Southern Hemisphere would decrease summer-fall Puelo River streamflows with significant impacts on salmon production, tourism and hydropower generation.
