Abstract：As part of the 3C-STAR (synthesized prevention techniques for air pollution complex and integrated demonstration in key city-cluster region) intensive observation, meteorological and air pollutant concentration measurements were performed in Conghua, Guangzhou and Kaiping in the Pearl River Delta (PRD) on Oct. 15 to Nov. 20, 2008. The features of air pollution meteorology over PRD during the intensive observation were analyzed. It was found that the typical types of weather condition associated with poor air quality over PRD during the intensive observation could be summarized into three types (pre-cold front, bottom of high pressure control, ridge of high pressure control). The pre-cold front type will lead the central and northeastern part of PRD polluted. The bottom of high pressure control type will lead the western part of PRD polluted. The ridge of high pressure control type will result in local air pollution of PRD. The air pollution of the city-cluster of PRD were closely related to the northeasterly prevailing wind with ground wind speed smaller than 2m/s, this situation will lead the southwestern part of PRD polluted for the accumulation of air pollutants transported by the prevailing wind.
