摘要
大气边界层是地球表面与大气之间水热、动量、能量和痕量气体等物质交换和输送的重要通道,在天气和气候的演变过程中有着重要作用。深厚大气边界层现象和特征、形成机理以及天气气候效应是大气边界层研究领域的热点问题,也是科学难题。着眼于对天气和气候高敏感、高影响的极端气候区和特殊地理区域,回顾梳理了深厚大气边界层的观测事实,归纳总结了不同地区深厚大气边界层的成因和影响因素,描述深厚大气边界层演变过程中独特的湍流运动图像,解析探讨了深厚大气边界层演变与沙尘滞空之间的关联。最后,提出了深厚大气边界层的未来研究关注重点和实现突破的4个关键科学问题,以期为更加系统地开展深厚大气边界层研究提供参考依据。
The atmospheric boundary layer connects the land surface to the atmosphere through the turbulent exchange of heat,momentum,and trace gases.In addition,it plays an important role in the formation and evolution of weather and climate.The characteristics and formation mechanisms of the deep atmospheric boundary layer have been key focus areas in atmospheric boundary layer research.Focusing on extremely arid regions and special geographical locations,the observational facts and influencing factors of the deep atmospheric boundary layer were reviewed and summarized.Furthermore,a physical description of turbulent motion in the development of the deep atmospheric boundary layer was provided.Using the Taklimakan Desert as an example,the effects of the interactions between the deep atmospheric boundary layer and dust stagnation on weather and climate were discussed.In order to provide a roadmap for future research,this study identified and outlined four key scientific problems related to deep atmospheric boundary layer research.
