摘要
利用 2 0 0 0 0 8～ 2 0 0 0 0 9渤海海上观测资料 ,初次揭示了渤海污染物浓度的时间变化特点 ,分析了光照、天气等因素对NOx、O3、SO2 和CO气体浓度的影响 .SO2 浓度比较稳定 ,浓度平均值在 0 0 0 6mg·m- 3左右 .O3浓度变化主要受辐射影响 .在弱天气形势下 ,CO和NOx 浓度分别在 2 5～ 3 5mg·m- 3和 0 1mg·m- 3左右 ,台风天气会造成浓度在短时间内的剧烈增长 .文中还简要说明了渤海大气污染与陆地污染的差异 ,评价了渤海夏季的空气质量 .
By using the observational data obtained over the Bohai sea in Aug.～Sep., 2000, the variation characteristics of NO x ,O 3,SO 2 and CO concentrations were firstly shown. The effects of solar radiation and weather conditions on the trace concentrations were analyzed. SO 2 concentration was very stable, its' average value was about 0 006 mg·m -3 . O 3 concentration was mainly controlled by solar radiation. The concentration of CO and NO x was around 2 5～3 5 mg·m -3 and 0 1 mg·m -3 ,respectively, in weak weathers. Typhoon weather may made their concentrations increasing abruptly in a short time. The distinct differences of the pollutant concentrations between land and sea were also revealed, and the air quality over the Bohai sea in summer season was assessed based on the measurements.
