海陆风对秦皇岛空气质量和颗粒物组分的影响OACSTPCD
Impact of Sea-land Breeze on Air Quality and Compositions of Particulate Matters in Qinhuangdao
为研究海陆风对秦皇岛市大气污染影响,基于气象和大气污染物观测数据,利用后向轨迹和气溶胶激光雷达研究了海陆风和非海陆风天气条件下颗粒物在水平传输和垂直输送方面的差异.研究结果发现,高浓度的PM2.5和O3主要对应西南风向.海陆风天气条件下,PM2.5浓度高于非海陆风天,各组分的浓度明显升高,秋季海陆风日O3浓度明显高于非海陆风日.秦皇岛市海陆风是否能够清除污染物取决于气团的路径.气团若经过秦皇岛以南污染排放区域,能够传输污染物,二次转化生成增强,导…查看全部>>
To study the impact of sea-land breeze on atmospheric pollution in Qinhuangdao,a research was conducted based on meteorological and atmospheric pollution observations.Backward trajectories and aerosol lidar were used to investigate the differences in horizontal transport and vertical conveying of particulate matters under sea-land breeze and non-sea-land breeze conditions.The findings revealed that high PM2.5 and O3 concentrations were present in the southwe…查看全部>>
