Workshop on Advances in Tropical Dynamics; Honolulu, Hawaii; January 14-15, 2014

该奖项为将于2014年1月14日至15日在夏威夷大学东西中心(EWC)举办的马登-朱利安振荡(MJO)研讨会提供支持。MJO是从印度洋传播到太平洋的有组织对流的包层，构成了热带地区季节内降水和大气环流变率的主要形式。MJO影响各种热带天气和气候现象，包括热带气旋(影响墨西哥湾的飓风)、亚洲、澳大利亚、非洲和美洲的季风和降雨量的开始和季节内波动，以及厄尔尼诺事件的开始。研讨会的目标是将从事MJO研究的研究人员聚集在一起，总结在理解MJO动力学方面的进展和仍然存在的挑战，并为未来协调的数值模拟实验制定计划。更具体地说，讲习班参与者将1)讨论和综合与热带动力学有关的最新理论、模拟和诊断突破；2)调查改善我们对热带动力学了解的剩余挑战和障碍，并讨论社区应对这些挑战的最佳途径；3)更新正在进行的MJO水行星间比较工作的状况。研讨会的预期成果是发表一份总结研讨会成果的论文，并“突出进展和未来的挑战”。EWC之所以被选为工作坊的地点，是因为预计工作坊的参与者将有大约一半来自亚洲。通过这一奖项提供的资金将用于资助通过公开竞争选出的约10名研究生和5名博士后的旅费。因此，该奖项将使处于职业生涯早期阶段的科学家能够与世界各地的MJO研究人员见面和互动，并使他们能够看到在国内可能无法获得的尖端成果和研究视角。除了与促进国际合作和支持早期科学家相关的更广泛的科学影响外，这项工作还具有社会价值，因为它将促进对MJO的理解，这是一种在世界各地具有多重社会影响的现象。

This award provides support for a workshop on the Madden-Julian Oscillation (MJO) to be held January 14-15 2014 at the East-West Center (EWC) at the University of Hawaii. The MJO is an envelope of organized convection that propagates from the Indian Ocean to the Pacific Ocean and constitutes the dominant form of intraseasonal precipitation and atmospheric circulation variability in the tropics. The MJO influences a variety of tropical weather and climate phenomena,including tropical cyclones (affecting hurricanes in the Gulf of Mexico), the onset and intraseasonal fluctuations of the monsoons and rainfall over Asia, Australia, Africa, and the Americas, and the onset of El Nino events. The goal of the workshop is to bring together the community of researchers engaged in MJO research to summarize the progress and remaining challenges in understanding the dynamics of the MJO, and to make plans for future coordinated numerical simulation experiments. More specifically, workshop participants will 1) discuss and synthesize recent theoretical, modeling, and diagnostic breakthroughs related to tropical dynamics; 2) survey remaining challenges and roadblocks to improving our understanding of tropical dynamics, and discuss the optimal paths forward for the community to address such challenges; and 3) update the status of the ongoing MJO aquaplanet intercomparison effort. A published paper summarizing the the workshop and "highlighting progress and future challenges" is an expected outcome of the workshop. The EWC is chosen as the venue for the workshop due to the expectation that about half of the workshop participants will come from Asia.The funds provided through this award will support travel for about 10 graduate students and 5 postdocs, to be chosen through an open competition. Thus, this award will enable scientists at the earliest stages of their careers to meet and interact with the worldwide community of MJO researchers, and enable them to see cutting-edge results and research perspectives which may not be available to them at home. Aside from the scientific broader impacts associated with promoting international collaboration and supporting early-career scientists, the work has societal value in that it will advance understanding of the MJO, a phenomenon which has multiple societal impacts around the world.
