Chapman Conference on Atmospheric Gravity Waves and their Effects on General Circulation and Climate; Honolulu, Oahu, Hawaii; February 27-March 4, 2011

这项拨款为学生和早期职业科学家参加查普曼会议提供旅费支持，该会议的主题是大气重力波及其对大气环流和气候的影响。查普曼会议是由美国地球物理联合会主办的专题会议，目的是促进对科学问题进行比大型会议更深入的讨论。本次会议将于2011年2月27日至3月4日在夏威夷大学东西方中心（瓦胡岛马诺阿校区）举行。这次会议的动机主要来自卫星测量和高分辨率建模的最新进展，这些进展导致了对重力波研究的兴趣激增，因为重力波的空间和时间尺度使它们难以在传统模型和数据集提供的分辨率下进行观察和研究。尽管它们的尺度很小，但它们的热量和动量输送对大尺度大气环流和地球表面气候的影响被认为是重要的，特别是在确定北半球极地涡旋的强度方面。这些效应已在气候和全球大气模式中参数化多年，但这些参数化不受观测的强烈约束，将受益于更高级的观测和波分辨模拟。这笔拨款具有学术价值，因为这次会议将为研究重力波及其对大气环流和气候的影响提供一个场所。这项资助将产生更广泛的影响，使学生和早期职业科学家能够参与会议，从而为下一代科学家的教育和培训提供支持。

This grant provides travel support for students and early-career scientists to attend a Chapman Conference on atmospheric gravity waves and their effect on the atmospheric general circulation and climate. Chapman conferences are topical metings held under the auspices of the American Geophysical Union to promote discussion of scientific issues on a deeper level than is possible at larger meetings. This conference would take place February 27-March 4 2011 at the East-West Center of the University of Hawaii (Manoa campus, Oahu). Motivation for the conference comes primarily from recent advances in satellite measurements and high-resolution modeling that have resulted in a surge of interest in research on gravity waves, since the spatial and temporal scales of gravity waves make them difficult to observe and study at the resolutions offered in traditional models and datasets. Despite their small scales, the effects of their heat and momentum transport on large-scale atmospheric circulation and the surface climate of the earth are thought to be significant, particularly in determining the strength of the polar vortex in the Northern Hemishere. These effects have been parameterized in climate and global atmospheric models for many years, but the parameterizations are not strongly constrained by observations and would benefit from more advanced observations and wave-resolving simulations.The grant has intellectual merit because the conference will provide a venue for examination of gravity waves and their impacts on atmospheric circulation and climate. The grant will have broader impacts by enabling the participation of students and early career scientists in the conference, thereby providing for the education and training of the next generation of scientists.
