RISDrought Recurrence in the Great Plains as Reconstructedfrom Long-Term Tree-Ring Records
Publisher: American Meteorological Society
Abstract: Recently collected tree-ring data were used to reconstruct drought from 1700 to the present in four regionsflanking the Great Plains. Regions were centered in Iowa, Oklahoma, eastern Montana and eastern Wyoming.Reconstructions ...
Secular Variations in Streamflow in the Western United States
Publisher: American Meteorological Society
Abstract: Long-term streamflow series in the western United States were examined for evidence of secular changes related to climate. Streamflow series contained appreciable low-frequency variation related to the combined influence ...
A New Assessment of Possible Solar and Lunar Forcing of the Bidecadal Drought Rhythm in the Western United States
Publisher: American Meteorological Society
Abstract: A new drought area index (DAI) for the United States has been developed based on a high-quality network of drought reconstructions from tree rings. This DAI is remarkably similar to one developed earlier based on much less ...
Spatial Patterns of Tree-Growth Anomalies in the United States and Southeastern Canada
Publisher: American Meteorological Society
Abstract: A network of 248 tree-ring chronologies in the conterminous United States is assembled and analyzed by rotated principal components analysis (RPCA) to delineate ?regions? of common tree-growth variation during the period ...
