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10亿人依赖亚洲季风降雨，但由于观测数据的差距，对其年际、年代际和百年尺度上的调制背后的动态的理解受到阻碍。厄尔尼诺Niño-Southern涛动，连同印度洋偶极子模式和其他现象，可能会在南亚和东南亚造成严重的干旱和洪水，这种情况可能会随着预测的变暖而加剧。缅甸周边地区似乎代表了亚洲季风主要组成部分之间的枢纽线或过渡，但到目前为止，大部分都没有记录。由于缅甸最近的政治变化，国际科学家现在可以进入缅甸，哥伦比亚大学拉蒙特·多尔蒂地球观测站和伍兹霍尔海洋研究所的这组研究人员是首批获得这种访问权的研究人员之一。这项研究将产生来自缅甸以及邻近的中国和泰国的柚木和其他物种的多种树木年轮记录，这些记录已被证明可以记录该地区的水文变化。实地和分析工作将由区域季风模拟研究加以补充。这项研究将为亚洲季风提供一些来自重要过渡带的第一手数据，从而改善目前对过去千年季风动力学的理解和建模。这些信息对未来的规划和减轻极端季风的影响至关重要。与缅甸、泰国、中国和新西兰的科学家建立了强有力的国际伙伴关系。pi将在哥伦比亚大学接待和培训几名亚洲合作者，并通过在伍兹霍尔海洋研究所的暑期实习为本科生提供研究经验。此外，该研究将继续向曼哈顿科学与数学中心的内城学生提供服务。项目的最后一年将在缅甸举办一个关于季风相关气候学的研讨会。这项研究的结果将特别直接关系到生活在亚洲季风直接影响下的脆弱人口的福利、粮食安全和森林管理需要。该基金由美国国家科学基金会国际和综合活动办公室共同资助。
