Signatures of land-atmosphere feedback in a 360-year tree-ring record

Randal D. Koster, NASA/GSFC, Greenbelt, MD; and H. C. Fritts and M. Suarez

A 360-year proxy (tree ring-based) temperature record spanning the continental United States provides a valuable, unparalleled opportunity to examine climate statistics associated with land-atmosphere feedback. Here, we demonstrate that the record does indeed contain certain established signatures of land-atmosphere feedback, particularly those associated with the variance and skew of summer air temperature. The lengthier data record provides support to the proposition that the land surface plays a key role in shaping continental air temperature variability.wrf recording  Recorded presentation
