摘要
采用风前、风中、风后3个阶段环境空气国控站点监测数据,结合同步气象数据分析可吸入颗粒物(PM10)、可吸入肺颗粒物(PM2.5)、二氧化硫(SO2)、二氧化氮(NO2)、一氧化碳(CO)、臭氧(O3)6种污染物不同阶段平均浓度变化规律,以及风速变化之后污染物浓度变化的滞后性,厘清大风过境天气过程中各种污染物浓度变化规律,为今后空气污染的预警预报提供了借鉴。
Using environmental air monitoring data before, in and after the wind from state-run stations, and also synchronous meteorological data, this paper analyzed mean concentration change rules of PM10.PM25. S02、 NO2, CO. O3 in different stages, and also the hysteresis of the pollutant concentration change after the change of wind velocity, providing references for sorting out change rules of pollutant concentrations in strong wind transit weather, and fore- casting the air pollution.
