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

研究人员量化了行星尺度波在高纬度中层气辉和温度中引起的变异，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。 结合在斯德哥尔摩大学的观测，他正在继续执行一项高纬度动力学和化学测量方案，扩大现有的羟基辐射和温度数据库，在这些数据库中观测到正常模式周期性及其瞬变。 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.
