Abstract:
This data set consists of reconstructed precipitation for Nevada Climate Division 3, annual July through June. Trees used for the reconstruction are bristlecone pine from Methuselah Walk, White Mountains, California. These data are archived with the ITRDB, filenames CA535.crn (standardized chronology) and CA535.rwl (ringwidth measurements). An extensive network of tree ring chronologies of greater than 1000 years in length exists for the western United States. This multi-millennial-length tree ring chronology network provides an excellent opportunity to study decadal to century scale variability in pre-instrumental times. There are now 80 long chronologies available that are sensitive to a wide variety of environmental variables, including warm season temperature and winter precipitation. In this study, 7979 years of annual (July-June) precipitation were reconstructed from bristlecone pine in the White Mountains of eastern California. The reconstruction documents the occurrence of eight multi-decadal droughts, with the two most recent centered on A.D. 924 and A.D. 1299. The occurrence of these two droughts is validated by an independent lake-level record from the neighboring Sierra Nevada Mountains. Droughts of this character, were they to occur today, would clearly have a devastating impact. Future work will focus on expanding the multi-millennial record of drought from tree rings and determining forcing mechanisms for these droughts.
