NSF East Asia and Pacific Summer Institute (EAPSI) for FY 2013 in Taiwan

这一行动资助了科罗拉多大学博尔德分校的Vu Nguyen于2013年夏天在台湾中礼的国立中央大学开展了一个地球科学研究项目。该项目的标题是“从下面产生的长周期行星波对高层大气的影响”。主持这项研究的科学家是Loren Chang博士。该研究项目调查行星波(在中低层大气中产生的全球范围的大气振荡)如何驱动高层大气的变化。它特别侧重于16天的行星波及其通过与大气层潮汐的非线性相互作用对高层大气的影响。该项目的第一阶段涉及在国家大气研究中心开发的大气环流模型中实施16天行星波。模式结果被用来确定16天行星波的影响传播到高层大气的主要机制。该项目的第二阶段将模型结果与气象学、电离层和气候星座观测系统(COSMIC)的观测结果进行比较，COSMIC是由台湾和美国联合资助的卫星任务。该项目的成果将提高我们对大气层作为一个完整系统的理解，并最终被用来对高层大气做出更好的预测，高层大气是一个拥有对科学进步和全球社会运转至关重要的空间技术的区域。EAPSI奖学金的广泛影响包括为研究员提供美国以外的第一手研究经验；对各自地点的科学、科学政策和科学基础设施的介绍；以及对社会、文化和语言的定位。这些活动符合NSF的目标，即在其科学家、工程师和教育工作者的职业生涯早期为国际合作进行教育，从而确保拥有一支具有全球意识的美国科学队伍。此外，在台湾逗留期间，所进行的研究将在一个国际会议上公布，以向广泛的全球受众传播信息。回到美国后，通过EAPSI奖学金获得的国际经验将与其他人分享，以鼓励未来参与该计划，并突出国际努力的好处。

This action funds Vu Nguyen of the University of Colorado at Boulder to conduct a research project in Geoscience during the summer of 2013 at National Central University in Jhongli, Taiwan. The project title is "Impacts on the Upper Atmosphere from Long Period Planetary Waves Generated from Below." The host scientist is Dr. Loren Chang.The research project investigates the ways in which planetary waves, global-scale atmospheric oscillations generated in the lower/middle atmosphere, can drive the variability of the upper atmosphere. It specifically focuses on the 16-day planetary wave and its effects on the upper atmosphere through nonlinear interactions with atmospheric tides. The first phase of the project involves the implementation of the 16-day planetary wave in an atmospheric general circulation model developed by the National Center for Atmospheric Research. Model results are utilized to identify the main mechanisms through which the effects of the 16-day planetary wave are transmitted to the upper atmosphere. The second phase of the project compares the model results to observations from the Constellation Observing System for Meteorology Ionospheric and Climate (COSMIC), a satellite mission funded jointly by Taiwan and the United States. The results of the project will improve our understanding of the atmosphere as a complete system and eventually be utilized to make better predictions for the upper atmosphere, a region housing space technology that is critical to the progress of science and the functioning of global society.Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. Furthermore, the research conducted will be presented at an international conference during the stay in Taiwan to disseminate the information to a broad, global audience. After arrival back in the United States, the international experience gained under the EAPSI fellowship will be shared with others in order to encourage future participation in the program and to highlight the benefits of international endeavors.
