Correlative MR Radar Studies of Large-Scale Middle Atmosphere Dynamics in the Antarctic

该项目将继续利用一些现有数据源分析南极上层中间层和下层热层（海拔70至100公里的MLT）的大气动力学，并继续与英国南极调查局积极合作，操作安装在罗瑟拉的MLT雷达，作为先前合同的一部分。Rothera MLT雷达产生水平风场的高分辨率测量，可以清楚地定义中性大气顶部的潮汐、行星波和重力波活动。这些数据将用于：(1)结合McMurdo、Davis和Syowa台站的类似数据集研究大尺度波浪动力学；(2)将Rothera MLT资料与卫星资料和德国南极站火箭探空项目的观测结果相结合，研究了中流层顶的区域结构；(3)通过与北半球数据集的相关研究来研究半球间和全球的联系。

This project will continue an analysis of the atmospheric dynamics in the antarctic upper mesosphere and lower thermosphere (MLT at altitudes of 70 to 100 km) from a number of existing data sources, and continue the active cooperation with the British Antarctic Survey in operating an MLT radar installed at Rothera as part of a prior award.The Rothera MLT radar produces high resolution measurements of the horizontal wind field that can define clearly the tidal, planetary wave, and gravity wave activity at the top of the neutral atmosphere. These data will be used to (1) investigate the large-scale wave dynamics in conjunction with similar data sets from McMurdo, Davis and Syowa stations; (2) investigate the regional structure of mesopause by combining Rothera MLT data with satellite data and the results of a rocketsonde program at the German antarctic station; and (3) investigate inter-hemispheric and global connections through correlative studies with northern hemisphere data sets.
