CEDAR: Temperature Variability in the High-Latitude Mesosphere: Normal Mode Oscillations and Wave-Wave Interactions

研究者量化了由行星尺度波引起的高纬度中间层气辉和温度的变化，并通过量化它们与重力波通量和潮汐振幅变化的关系来确定波特征的性质。与斯德哥尔摩大学的观测相结合，他正在继续进行高纬度动力学和化学的测量项目，扩展现有的羟基辐射和温度数据库，在这些数据库中观察到正常模式的周期性和它们的瞬态。此外，他正在分析测量结果，以确定中间层长期温度和成分变化的时间历史。

The investigator quantifies the variability induced in the high-latitude mesospheric airglow and temperature by planetary-scale waves, and determines the nature of wave signatures by quantifying their relationship to variations of gravity-wave flux and tidal amplitudes. In conjunction with observations at Stockholm University, he is continuing a measurement program of high latitude dynamics and chemistry, extending the existing data base of hydroxyl radiance and temperature where normal mode periodicities and their transience is observed. In addition, he is analyzing measurements to identify the time history of long-period temperature and composition variations in the mesosphere.
