摘要: 空天过渡区是指传统航空活动和航天活动过渡区域,本文指距离地表50公里至150公里的大气圈层。近年来随着空天一体化空间环境应用服务加快布局,空天过渡区大气环境认知和建模预报研究愈来愈受到多学科广泛重视,空天过渡区大气扰动微物理过程和机理研究取得了较为显著的进展。本文梳理了近年空天过渡区大气动力学研究现状,简述了太阳/太阳风–磁层–空天过渡区的耦合链式过程中,太阳辐射和极区粒子沉降对空天过渡区大气环境影响的研究进展。然后从重力波、行星波、潮汐波和典型低层大气活动四个角度出发,重点分析和总结地球活动/低层大气扰动对空天过渡区大气环境影响的研究进展。最后展望空天过渡区未来的发展前景及需要解决的几个关键问题,为大气科学和空间物理学者提供一定参考。Abstract: The aerospace transition zone refers to the region between traditional aviation and space activities, specifically the atmospheric layer from 20 kilometers to 150 kilometers above the Earth's surface. With the accelerated development of aerospace integrated space environment services, the modeling and forecasting of atmospheric dynamics in the aerospace transition zone have received increasing attention from various disciplines while significant progress has been made on the microphysical processes and mechanisms of the aerospace transition zone atmospheric disturbances. This study reviews the recent research status of the aerospace transition zone atmospheric dynamics, and briefly analyzes the research progress on the impact of solar radiation and polar particle precipitation on the aerospace transition zone atmospheric environment in the coupling chain process of the Sun/solar wind–magnetosphere–the aerospace transition zone. Then, we focus on summarizing the research progress of the coupling between Earth activities-lower atmosphere and the aerospace transition zone by four aspects of gravity waves, planetary waves, tidal waves, and typical lower atmospheric activities. Finally, it looks forward to the future development prospects of the aerospace transition zone and several key issues that need to be solved, providing a certain reference for scholars in atmospheric science and space physics.
