摘要
Abstract
Based on the air quality index( AQI) data from the tianqihoubao website and the meteorological parameters data from the HKUST website as well as HYSPLIT-WEB model utilization, the typical Air pollution processes and cleaning process in 2014 were compared to describe the relationship of air pollution and meteorological factors. The results showed that there was a strong synchronization in typical air pollution process in the three cities, a little delay in Zhuhai however. Moreover, the dominant pollutant changed as Air Quality Index ( AQI) . Air pollution was closely connected with weather process: the typical pollution processes were caused by Continental anticyclone which changed and removed to ocean in January and by the peripheral subsidence airflow of typhoon systems in July. Compared with the cleaning process, the speed of surface layer in haze process was smaller and there occurred Inversion, which were against the transportation and dispersion of pollutants. The interaction effect of air pollution of cities in PRD was further confirmed by HYSPLIT model, which also showed there was a delay in Zhuhai due to the location in downwind direction.关键词
