This award will enable a five-year project using the science of dendrochronology to examine the relationship between the Asian monsoon and the large-scale coupled processes that drive much of its variability. The researchers will examine these interactions on inter-annual to centennial time scales and anticipate that this project will yield information about how the monsoon system has varied over the past several centuries. Specifically, they will investigate the relationship of the Asian Monsoon to the large-scale coupled processes that drive much of its variability; namely air temperatures and sea surface temperatures (SST).The project is motivated by a series of research question such as: "How have the processes responsible for driving much of the observed Asian monsoon climate dynamics varied and interacted on inter-annual to centennial time scales?" and "How have Asian surface air temperatures, Indian Ocean SSTs, and Tropical Pacific SSTs covaried and interacted over the past several centuries?" The Asian monsoon climate system plays a significant role in large-scale climate variability over much of the globe. Due to its considerable importance to global climate and implications for the world's population, a greater understanding of this system, with the ultimate goal being improved prediction on annual to decadal and longer time scales is warranted.This research will help the science community understand climate variability in a densely populated region of the world. On the practical side, improved knowledge of climate variability could be used to improve long-term agricultural planning in the region by buffering agrarian societies against the effects of monsoon variability. The award will support post-doctoral, graduate, and undergraduate students at Columbia University and the Lamont Doherty Earth Observatory and help build scientific capacity, infrastructure, and professional partnerships among Asian colleagues.

该奖项将使一个五年的项目使用Dendrochology科学，以研究亚洲季风与大规模耦合过程之间的关系，从而驱动其大部分可变性。 研究人员将检查这些相互作用在年间至百年纪念尺度上，并预测该项目将产生有关季风系统在过去几个世纪中如何变化的信息。 具体而言，他们将调查亚洲季风与大量变异性的大规模耦合过程的关系；即空气温度和海面温度（SST）。该项目是由一系列研究问题的动机，例如：“如何驱动所有观察到的亚洲季风气候动态的过程如何变化，并在年间到百年纪念时间进行互动秤？”和“过去几个世纪以来，亚洲地表空气温度，印度洋SSTS和热带太平洋SST之间如何协变和相互作用？”亚洲季风气候系统在全球大部分地区的大规模气候变化中起着重要作用。 由于它对全球气候的重要性及其对世界人口的影响，因此有必要对该系统有更深入的了解，而最终的目标是改善对年度际交往和更长时间尺度的预测。这项研究将帮助科学界了解气候变异性在人口稠密的世界中。 在实际方面，可以通过缓冲农业社会来防止季风可变性的影响来改善气候变异性知识来改善该地区的长期农业规划。 该奖项将支持哥伦比亚大学和拉蒙特·多尔蒂（Lamont Doherty）地球天文台的博士后，研究生和本科生，并帮助建立科学能力，基础设施以及亚洲同事之间的专业合作伙伴关系。
