More than a billion people depend upon the Asian monsoon rains, but understanding the dynamics behind its modulations on interannual, decadal and centennial scales is hampered by gaps in observational data. The El Niño-Southern Oscillation, along with the Indian Ocean Dipole Mode and other phenomena, can cause severe drought and flood conditions over South and Southeast Asia, which may intensify with projected warming. The region surrounding Myanmar appears to represent a hinge line or transition between major components of the Asian monsoon, but until now has remained largely undocumented. Due to recent political changes Myanmar is now accessible to international scientists, and this team of researchers from the Lamont Doherty Earth Observatory of Columbia University and the Woods Hole Oceanographic Institution is among the first to gain such access. This research will generate multiple tree-ring records from teak and other species in Myanmar and adjacent China and Thailand that have been shown to document hydrological variability in the region. The field and analytical work will be complemented by modeling studies of the regional monsoon. The research will provide some of the first data from an important transitional zone for the Asian monsoon, thereby improving present understanding and modeling of monsoon dynamics over the past millennium. This information is critical for future planning and mitigation of monsoon extremes. There are strong international partnerships with scientists from Myanmar, Thailand, China, and New Zealand. The PIs will host and train several Asian collaborators at Columbia University and offer research experience for undergraduate students through summer internships at the Woods Hole Oceanographic Institution. In addition, the research will continue their outreach to inner city students from the Manhattan Center for Science and Mathematics. A workshop in Myanmar on monsoon-related climatology will be conducted in the project's final year. The results of this research will be particularly and directly relevant to the welfare, food security and forest management needs of those vulnerable populations who live within the direct influence of the Asian monsoon.This grant is being co-funded by NSF's Office of International and Integrative Activities.

超过十亿人依赖亚洲季风的降雨，但是了解其对年龄段，十分和百年纪念尺度的调制背后的动态受到观察数据中的差距的阻碍。厄尔尼诺南部振荡以及印度洋偶极子模式和其他现象，可能会导致南亚和东南亚的严重干旱和洪水条件，这可能会随着预计的变暖而加剧。缅甸围绕的地区似乎代表了亚洲季风的主要组成部分之间的铰链线或过渡，但到目前为止，仍然没有记录在很大程度上。由于最近的政治变化，国际科学家现在可以进入缅甸，而来自哥伦比亚大学拉蒙特·多尔蒂（Lamont Doherty）地球观测团和伍兹霍尔海洋学机构（Woods Hole Oceanographic Institution）的这支研究人员是最早获得此类通道的人。这项研究将在缅甸以及邻近的中国和泰国产生多个树木环记录，这些记录已被证明记录了该地区的氢变异性。该领域和分析工作将通过对区域季风进行建模研究来完成。该研究将为亚洲季风提供一些重要的过渡区域中的一些第一个数据，从而改善了过去千年中对季风动态的当前理解和建模。此信息对于未来的计划和缓解季风极端至关重要。与来自缅甸，泰国，中国和新西兰的科学家建立了牢固的国际伙伴关系。 PIS将在哥伦比亚大学接待和培训几位亚洲合作者，并通过伍德斯霍尔海洋学机构的夏季国际职业为本科生提供研究经验。此外，该研究将继续从曼哈顿科学与数学中心向内城的学生宣讲。该项目的最后一年将在缅甸举行的有关季风相关气候学的研讨会。这项研究的结果将特别是直接与居住在亚洲季风直接影响的脆弱人群的福利，粮食安全和森林管理需求有关。这笔赠款是由NSF国际和综合活动办公室共同资助的。
