A multi-century reconstruction of May precipitation for the
Mid-Atlantic Region using Juniperus virginiana tree rings.
Journal of Climate, Early Online Release 20 September 2011.
doi: http://dx.doi.org/10.1175/JCLI-D-11-00017.1
We present a multi-century reconstruction of May precipitation
(1200 - 1997) for the Mid-Atlantic Region of the United States.
The reconstruction is based on the first principal component (PC1)
of two millennial-length Juniperus virginiana L. (eastern redcedar)
tree-ring chronologies collected from rocky, limestone sites in
the Ridge and Valley province of West Virginia. A split-calibration
linear regression model accounted for 27% of the adjusted variance
in the instrumental record and was stable through time. The model
was verified by the reduction of error (RE = 0.21) and coefficient
of efficiency (CE = 0.20) statistics. Multi-decadal changes in
precipitation were common throughout the reconstruction, and wetter
than median conditions and drier than median conditions occurred
during the Medieval Climate Anomaly (1200 - 1300) and the Little
Ice Age (1550 - 1650), respectively. The full reconstruction
contained evidence of inter-annual and decadal variability;
however, the 20th century recorded the greatest number of decadal
extreme wet and dry periods. A comparison of the May precipitation
reconstruction to other regional reconstructions of Potomac River,
Maryland streamflow (Cook and Jacoby 1983), Virginia/North Carolina
July Palmer Hydrologic Drought Index (PHDI; Stahle et al. 1998),
Missouri July PHDI (Cleaveland and Stahle 1994), and White River,
Arkansas streamflow (Cleaveland 2000) showed that eastern US decadal
drought and pluvial events extended into the Mid-Atlantic Region.
A positive correlation between PC1 and the winter North Atlantic
Oscillation (NAO) Index and comparisons of smoothed May precipitation
and NAO (Luterbacher et al. 1999) indicated that J. virginiana's
response to May precipitation was mediated by winter temperature.
STUDY NOTES: Reconstruction of May precipitation for AD 1200-1997
for the Mid-Atlantic Region of the United States.
The reconstruction is based on two Juniperus virginiana L.
(eastern redcedar) tree-ring chronologies collected in
West Virginia.
