青藏高原大气边界层结构及其发展机制研究

Research on the Atmospheric Boundary Layer Structure and Its Development Mechanism in the Tibetan Plateau

研究青藏高原大气边界层对于我们认识其地面的热量与水分收支状况,了解高原及其周边地区的天气和气候变化具有重要意义。然而,高原大气边界层观测资料的匮乏制约着青藏高原的天气与气候研究。首先,梳理了针对青藏高原大气边界层的大气科学试验情况;其次,归纳了青藏高原大气边界层的高度与风场结构、温度与湿度场结构的研究进展,并从热力学和大气动力学角度介绍了大气边界层的发展机制,在此基础上,对目前研究中存在的不足进行了探讨,指出青藏高原大气边界层的研究还处于揭示现象阶段,对发展机制的研究不够深入,对整个高原面上不同区域同一时间的联动研究较少。针对上述不足之处对未来的研究方向进行了展望。

Studying the atmospheric boundary layer over the Tibetan Plateau is of great significance for understanding the heat and water budget,weather,and climate change of the plateau and its surrounding areas.However,the research on the weather and climate of the Tibetan Plateau is restricted by the lack of observational data.The atmospheric science experiments on the atmospheric boundary layer over the Tibetan Plateau were reviewed in the present study.Furthermore,the research progress on the height,wind field structure,temperature,and humidity field structure of the atmospheric boundary layer over the Tibetan Plateau was summarized,and the development mechanism of the atmospheric boundary layer was introduced from the perspectives of thermal and atmospheric dynamics.Accordingly,the shortcomings of the current research in this field were discussed,and it was highlighted that the research on the atmospheric boundary layer of the Tibetan Plateau is still in the exploration stage and that the research on the development mechanism is not thorough enough.Few studies have simultaneously examined the linkages between different regions on the plateau at the same time.Finally,considering the aforementioned shortcomings,future developments have been proposed.
