Holly L. Faulstich, Connie A. Woodhouse, Daniel Griffin. 2013. Reconstructed cool- and warm-season precipitation over the tribal lands of northeastern Arizona. Climatic Change, Published Online 21-November-2012. DOI: 10.1007/s10584-012-0626-y
For over a decade, the Hopi Tribe and Navajo Nation of northeastern Arizona have suffered the effects of persistent drought conditions. Severe dry spells have critically impacted natural ecosystems, water resources, and regional livelihoods including dryland farming and ranching. Drought planning and resource management efforts in the region are based largely on the instrumental climate record, which contains a limited number of severe, sustained droughts. In this study, a new network of moisture-sensitive tree-ring chronologies provides the basis for evaluating the longer-term temporal variability of precipitation in the Four Corners region. By analyzing the earlywood and latewood components within each annual tree ring, we are able to generate separate, centuries-long reconstructions of both cool- (October-April) and warm-season (July-August) precipitation. These proxy records offer new insights into seasonal drought characteristics and indicate that the instrumental record fails to adequately represent precipitation variability over the past 400 years. Through the use of two different analysis techniques, we identify multiyear and decadal-scale drought events more severe than any in the modern era. Furthermore, the reconstructions suggest that many of the historically significant droughts of the past (e.g., 17th century Puebloan drought) were not merely winter phenomena, but persisted through the summer season as well. By comparing these proxy records with historical documents, we are able to independently validate the reconstructions and better understand the socioeconomic and environmental significance of past climate anomalies on the tribal lands of northeastern Arizona.
STUDY NOTES: A network of nine Douglas-fir (Pseudotsuga menziesii) and six ponderosa pine (Pinus ponderosa)
chronologies from the Four Corners region were updated through the 21st century for this study.
Earlywood and latewood widths widths were measured on both the archived and newly collected
tree-ring samples. Stepwise multiple linear regression was used to generate reconstruction
models by calibrating the tree-ring chronologies with seasonal precipitation data over their
common period (1896-2008 AD). Centuries-long reconstructions of both cool- (October-April)
and warm-season (July-August) precipitation were generated.
