CEDAR: Comparative Mesospheric Gravity Wave Activity Observed Along a Chain of Sub-Tropical to Mid-Latitude MF Radars

通过对中层风纬向变化的气候学研究，研究者阐明了从对流层顶到中层的波活动耦合，以及重力波对中层的差异强迫。 她使用了一年的数据，这些数据是从一系列覆盖亚热带和中纬度地区的中频雷达收集的。 她的综合研究比较了纬度链上每个站的中层波动活动的气候变化。 这些比较提供了波浪活动的纬度变化的定量测量。 简单的模型，评估其准确再现中层波活动的特点，包括波的传播，饱和和临界层过滤。 Thorsen正在通过澄清控制风变化的主导机制（当通过雷达观察时）来帮助未来的建模工作。

Through climatological studies of the mesospheric wind latitudinal variation, the investigator clarifies wave activity coupling from the tropopause to the mesosphere, and differential forcing of the mesosphere by gravity waves. She uses one year worth of data, collected from a chain of medium frequency radars spanning sub-tropical and mid-latitude regions. Her comprehensive study compares the climatological variability of mesospheric wave activity at each station in the latitude chain. These compares provide quantitative measures of the latitudinal variation of wave activity. Simple models, assessed for their accurate reproduction of the mesospheric wave activity's characteristics, incorporate wave propagation, saturation and critical layer filtering. Thorsen is aiding future modeling efforts, by clarifying the dominant mechanisms controlling wind variance (when observed by radar).
