大气边界层的国内外研究现状

Domestic and Abroad Research Status of Atmospheric Boundary Layer

对大气边界层的理论基础、确定方法、特征要素、影响因子、时空变化特征以及与大气污染间的相互作用进行总结,得出以下结论:大气边界层的理论体系较为完备,但理论研究进展缓慢;廓线测量是确定大气边界层结构最常用的方法,雷达、数值模拟等方法仍需对比验证;大气边界层日变化、季节变化特征十分明显,海陆间边界层变化特征差异明显,戈壁、高原等地区的大气边界层特征较为特殊;大气边界层结构,尤其是风速风向、混合层高度对大气环境有明显的影响;大气污染对大气边界层的影响和区域大气边界层特征的研究较少,可作为今后的研究重点。

Summarized the theoretical basis, methods to determine, characteristic factors, impact factors, space-time characteristics of variation of the atmospheric boundary layer and the interac-tion between the structure of atmospheric boundary layer and the air pollution. Results showed that： （a） The theory of atmospheric boundary layer has a complete theoretical system and the theoretical research develops slowly. （b） Profile measurement is the most common method to determine the structure of ABL, other methods such as radar and numerical simulation still need verification. （ c） The diurnal and seasonal variation characteristics of the atmospheric boundary layer are very obvious, characteristics of variation between sea and land are obviously different, characteristics of ABL in gobi, plateau are special. （ d） The influences caused by the structure of ABL, especially speed and direction of wind and PBL to air quality are obvious. （ e） The research on the influence of atmospheric pollution on ABL and regional characteristics of ABL is less, it could be the focus of research in the future.
