This award seeks to develop millennium-length estimates of the strength of Asian monsoon atmospheric circulation and to infer variability in past monsoon circulation from replicated, annually-resolved stable oxygen isotope time series from the long-lived southeast Asian conifer Fokienia hodginsii in Vietnam and Laos. The research leverages a previously supported pilot study that demonstrated that tree-ring isotopes from this species in this region responds to broad-scale patterns of Asian monsoon circulation that are consistent with climate dynamics, known controls on the stable isotopes of precipitation, and the physical and chemical mechanisms comprising the study of isotope dendroclimatology.The potential broader impacts include supporting undergraduates in the planned research and providing a potentially important new archive of data from a climatologically sensitive region.

该奖项旨在发展亚洲季风大气循环强度的千年长度估计值，并从季风循环中从越过长期寿命的东南亚针叶树福基尼亚霍奇尼亚（Fokienia fokienia forokienia forkienia forkienia forkienia）中推断出过去的季风循环中的可变性。 。 该研究利用了一项先前支持的试验研究，该研究表明该地区的该物种的树环同位素对亚洲季风循环的广泛模式做出了反应，这些模式与气候动力学一致，已知的对降水稳定的同位素的控制以及物理的稳定同位素的控制。以及包括同位素树突气候学研究的化学机制。潜在的更广泛的影响包括在计划研究中支持本科生，并提供了来自气候敏感地区的潜在重要的数据档案。
