本项目中我们将通过分析SABER/TIMED卫星观测资料和地基激光雷达观测数据研究中间层逆温的基本特征，并结合数值模拟方法定量评估各种大气波动对逆温温度增强的贡献，探寻中间层逆温的关键形成机制。在此基础上，结合无线电探空仪、激光雷达和COSMIC掩星给出的低层大气温度资料，研究中间层逆温发生时低层大气热结构变化，辨明大气不同层区结构与扰动的关联，探寻低层大气与中间层大气的耦合机制。本项目的研究将增进人们对大气热结构与变化、以及大气不同层区之间能量耦合过程的认知。

In this project, the primary scenarios of mesospheric inversion layers are going to be investigated by analyzing the data from SABER/TIMED and ground-based lidars. Based on these observations and numerical simulations, we hope to quantitatively estimate the contributions of kinds of atmospheric waves to the temperature enhancement in mesospheric inversions, and then reveal the main origins of mesospheric inversions. Furthermore, by analyzing the data from radiosonde, lidars and COSMIC RO, the lower atmospheric temperature and its variation during the mesospheric inversion are going to be studied to reveal the link and coupling between the lower atmosphere and mesosphere. The proceeding of this project will be helpful for our comprehensive understanding of the atmospheric thermal structure and its variability, and the energy coupling among different atmospheric layers.
