低层大气，中间层大气以及热层大气各圈层相互耦合研究是近年来日地空间物理重要的前沿研究课题。本项目我们利用自主研制的独特的双层全天空气辉观测网以及国家大科学工程子午工程地基观测数据，同时借助于卫星和再分析数据，并结合数值模拟，研究台风产生的重力波在中间层大气空间传播和时间演化规律, 掌握其动量和能量输运机制；研究台风产生的环形重力波对背景风场的加速/减速机制；揭示台风产生的重力波在中间层区域破碎产生的次级波在热层/电离层的传播演化机理；探究低层大气，中间层大气以及热层大气相互耦合机制。本项目的研究成果将为日地空间天气链路上的低层，中间层和热层大气相互耦合提供新的认识，为空间灾害性预报模式提供理论基础。

The coupling between the lower atmosphere, the middle atmosphere and the upper atmosphere is an important research topic in the field of space physics in recent years. The self-developed, unique double all sky airglow observation networks data and the meridian project ground based observation data, satellite and reanalysis data, combined with numerical simulation will be used in this project. To study the spatial and temporal evolution of gravity waves generated by typhoons in the mesosphere, to grasp the momentum and energy transport mechanism; to study the acceleration/deceleration mechanism of the background wind field by the gravity waves; to reveal the propagation and evolution mechanism of the thermosphere/ionosphere secondary waves generated by the breakup of gravity waves in the mesosphere region; to explore the coupling mechanism of the lower atmosphere, the middle atmosphere and the thermosphere atmosphere. The research results of this project will provide new insights for the coupling of the lower atmosphere, the middle atmosphere and the thermosphere in the solar terrestrial space synoptic link, and provide a theoretical basis for the spatial disaster prediction mode.
