CEDAR: Equatorial and Global Studies of Large-Scale Dynamics Using MF Radar

该项目在南半球副热带地区安装了一个新的中频雷达，用于赤道和全球中间层和低热层大尺度动态的相关研究。 该雷达位于南半球的一个地点，与在夏威夷运行的一个类似系统相配合，将在一个目前没有测量能力的地点提供对大气潮汐结构的灵敏度。 PI将使用来自新的和现有的雷达的数据来检查半球间的潮汐结构和变化，低层大气中源变化的潮汐响应，以及MLT中其他行星尺度运动的全球结构和纬向波数。 赤道和亚热带潮汐变率的分析密切联系到当地潮汐强迫的大气响应的并行数值研究，使潮汐变率的原因定量的了解。

This project installs a new MF radar in the subtropical southern hemisphere and for use in correlative studies of large-scale dynamics of the equatorial and global mesosphere and lower thermosphere (MLT). The radar, located at a southern hemisphere site conjugate to a similar system operating in Hawaii, would provide sensitivity to atmospheric tidal structures in a location with no present measurement capabilities. The PI will use data from new and existing radars to examine interhemispheric tidal structure and variability, tidal responses to source variations in the lower atmosphere, and global structure and zonal wave numbers of other planetary-scale motions in the MLT. Analyses of equatorial and subtropical tidal variability closely link to parallel numerical studies of the atmospheric responses to local tidal forcing, enabling a quantitative understanding of the causes of tidal variability.
