华北大气边界层结构演变对污染扩散的影响分析OACHSSCD
Analysis of Influence of Atmospheric Boundary Layer Structure Evolution on Pollution Diffusion in North China
大气边界层作为污染物与大气环境相互作用的关键区域,其结构演变直接影响污染物的扩散能力和传输效率.通过分析华北地区边界层结构的时空变化,建立边界层高度与PM2.5 质量浓度的统计关系模型,揭示了边界层演变对污染物扩散的影响机制.研究表明,PM2.5 质量浓度与边界层高度之间存在显著的负相关关系.
The atmospheric boundary layer,as a key region for the interaction between pollutants and the atmospheric environment,directly influences the diffusion capacity and transport efficiency of pollutants.By analyzing the spatiotemporal variations in boundary layer structure in North China,a statistical relationship model between boundary layer height and PM2.5 mass concentration is established,revealing the impact mechanism of boundary layer evolution on pollutant dispersion.The study demonstrates a significant negative correlation between PM2.5 mass concentration and boundary layer height.
