dc.description.abstractThe main purpose of this project has been to increase our understanding of drought history of the western United States through the use of tree rings. Accordingly, we reconstructed the Palmer Drought Severity Index (PDSI) in the western United States back to A.D. 1700 from 40 tree-ring series. In addition, we studied the joint occurrence of drought in the western United States and sea surface temperatures (SST) anomalies in the eastern North Pacific. To derive a long term SST record we reconstructed SST off Baja California from tree-ring records in Mexico and the southwestern United States. From a comparison of the SST reconstruction with the PDSI reconstruction we found that anomalously cold SST in spring and early summer appears to be related to large scale spring and summer drought in western United States.
