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

该奖项将为2014年1月14日至15日在夏威夷大学东西方中心（EWC）举行的马登-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络层，构成了热带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的开始和季节内波动，以及厄尔尼诺现象的开始。研讨会的目的是将从事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，研讨会参与者将1)讨论和综合最近与热带动力学相关的理论、建模和诊断方面的突破；2)调查当前存在的挑战和障碍，以提高我们对热带动力学的理解，并讨论解决这些挑战的最佳途径；3)更新正在进行的MJO水行星相互比较工作的状态。本次研讨会的预期成果是发表一篇总结研讨会并“突出进展和未来挑战”的论文。之所以选择EWC作为研讨会的举办地，是因为预计将有一半左右的与会者来自亚洲。通过该奖项提供的资金将用于支持通过公开竞争选出的约10名研究生和5名博士后的旅行。因此，该奖项将使处于职业生涯早期阶段的科学家能够与全球MJO研究人员社区见面并进行互动，并使他们能够看到他们在国内可能无法获得的前沿成果和研究观点。除了与促进国际合作和支持早期职业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，这一现象在世界各地具有多重社会影响。

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.
