Building on a previous NSF award, the PI will acquire U.S. high-resolution radiosonde data for gravity wave analysis. This work will give new results on the information content of 30 m resolution radiosonde observations with a view to gravity wave influences on the mean atmospheric state, the interannual variability of gravity waves in the troposphere and lower stratosphere, and the sources and propagation of gravity waves. As a second focus, the underlying physics that determine the formation and maintenance processes for the tropical and extra-tropical tropopause will be examined. In addition to fulfilling the needs of the research project, the collection of radiosonde data will be made available to the international research community in the database that is maintained by the PI through a web-site on behalf of the World Climate Research Programme. Two graduate students and an undergraduate student will participate in the research.

在之前NSF授予的基础上，PI将获得美国高分辨率无线电探空仪数据，用于重力波分析。这项工作将在30米分辨率无线电探空仪观测的信息内容方面得出新的结果，以期了解重力波对平均大气状态的影响、对流层和平流层下部重力波的年际变化以及重力波的来源和传播。作为第二个重点，将审查决定热带和热带外对流层顶形成和维持过程的基本物理学。除了满足研究项目的需要外，无线电探空仪收集的数据将通过一个网站提供给国际研究界，该数据库由PI代表世界气候研究方案维护。两名研究生和一名本科生将参与这项研究。
