我国中高层大气观测研究的新进展

NEW ADVANCES OF MIDDLE AND UPPER ATMOSPHERE RESEARCH IN CHINA

中高层大气是与人类生存环境关系极为密切、又易受太阳活动影响的层次，它的研究在日地物理研究中占有特殊的地位．近年来，我国在中高层大气行星波、重力波、光化过程和太阳活动与人类活动影响等方面取得了可喜的进展，获得一系列重要成果；在观测方面，VHF雷达、钠荧光激光雷达、中间层大气毫米波探测和倾斜滤光片光度计等一批新型观测设备投入使用，增强了对中高层大气的探测能力.本文重点介绍了近年来我国在高平流层、中间层和低热层大气方面的主要研究情况．

The middle and upper atmospheric research has a special position in the solar-terrestrialphysics owing to the fact that it is close relationship with human life environment and easy to beeffected by solar activity. In recent years, the studies of planetary waves, gravity waves,phOtochemical processes and effects of solar and anthroPOlogical activities etc. in China have madeencouraging progress. In the observation, some new instrumentations, e. g., VHF radar,odium lidar, mesospheric microwave measurements and tilting filter photometer etc. havebeen bring intO operation, it enhances the observing ability to middle and upper atmospheregreatly. Main progress of the researh in the upper stratOSphere, mesosphere, and lOWerthermosphere in China during recent years is reviewed in this paper.
