大气波动监测仪在岩石圈-大气层-电离层研究中的应用

Application of Atmospheric Disturbances Monitor on Lithosphere-atmosphere-ionosphere Coupling

针对北京大学空间物理与应用技术研究所研制的两台大气波动监测仪近三年的观测数据,对这一时段内所观测到的重力波和次声波周期尺度扰动的形态特征、谱结构特征及其在时间分布上的统计特征进行了分析.给出了几例雷暴、地震等事件中观测到的大气扰动,并揭示了这些事件期间观测到的与地面大气扰动周期尺度相类似的电离层扰动.结果表明,北京大学研制的大气波动监测仪可有效记录到地面的微弱大气扰动,观测数据可用于进行岩石圈-大气层-电离层之间的耦合研究.

Gravity waves and infrasonic waves play important roles in the coupling of lithosphere,atmosphere and ionosphere.This paper analyzes the observational data of Atmospheric Disturbances Monitors,which are developed by Institute of Space Physics and Applied Technology,Peking University.The morphological features and spectral structures of the observed gravity waves and infrasonic waves are presented,then their temporal distribution characteristics are summarized.We also have done some case studies about thunderstorms and earthquakes.The disturbances of atmosphere recorded by Atmospheric Disturbances Monitor and the similar observations of ionospheric disturbances during these events are presented.These results reveal that Atmospheric Disturbances Monitor could record the week disturbance of the surface atmosphere,proving which a useful tool for study of Lithosphere-Atmosphere-Ionosphere coupling.
