Abstract ATM-9729571 Woodhouse, Connie A. University of Colorado Title: Expanded Dendroclimate Reconstruction of Great Plains and Central Rocky Mountains Drought This award supports research to: 1) reconstruct spatial and temporal patterns of drought in the central Rocky Mountains and central High Plains through dendroclimatic reconstructions of Plains drought back at least 700-1000 years and South Platte and Arkansas River basin snowpack back at least 300 years, and 2) characterize and examine relationships between atmospheric circulation patterns that have accompanied droughts related to both low snowpack and lack of growing season moisture over the past centuries. This work will provide an expanded temporal context from which to evaluate the variability of seasonal precipitation, and thus water supply, as well as provide information about the influence of atmospheric circulation features on drought variability in the region.

伍德豪斯，康妮a科罗拉多大学标题：大平原和落基山脉中部干旱的扩展树木气候重建该奖项支持以下研究：1)通过对至少700-1000年前的平原干旱和至少300年前的南普拉特和阿肯色河流域积雪的树木气候重建，重建落基山脉中部和中部高平原干旱的时空格局；2)表征和研究过去几个世纪以来伴随低积雪和生长季节缺乏水分的干旱的大气环流模式之间的关系。这项工作将提供一个扩大的时间背景，以此来评价季节性降水的变化，从而评价供水，并提供关于大气环流特征对该区域干旱变化的影响的信息。
