| 中文摘要 |
| 利用2000-08～2000-09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0.006 mg·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2.5～3.5 mg·m-3.和0.1 mg·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. |
| 英文摘要 |
| By using the observational data obtained over the Bohai sea in Aug.～Sep., 2000, the variation characteristics of NOx ,O3,SO2 and CO concentrations were firstly shown. The effects of solar radiation and weather conditions on the trace concentrations were analyzed. SO2 concentration was very stable, its' average value was about 0.006 mg·m-3 . O3 concentration was mainly controlled by solar radiation. The concentration of CO and NOx 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. |
