United States High-Vertical Resolution Radiosonde Data Analysis for Gravity Waves and Tropopause Processes and Dissemination to the Science Community

在之前NSF奖项的基础上，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。这项工作将从重力波对平均大气状态的影响、对流层和平流层低层重力波的年际变化以及重力波的来源和传播等方面，对30m分辨率探空仪观测的信息量作出新的结果。作为第二个重点，将研究决定热带和热带外对流层顶形成和维持过程的基本物理。除了满足研究项目的需要外，无线电探空数据的收集还将在国际研究界的数据库中提供给国际研究界，该数据库由国际和平研究所通过代表世界气候研究方案的网站维护。两名研究生和一名本科生将参与这项研究。

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.
