【摘要】 广州是珠三角的核心地区,目前光化学污染较为严重。本文利用2004年1-2月在广州市中心的中山大学地环大楼楼顶监测的光化学前体物CO、SO₂、NOy和O₃高密度的连续自动监测数据及风向、风速、温度、空气污染指数（API）资料,研究广州市光化学前体物浓度与气象条件的关系,初步结果表明,冷空气活动对广州市冬季光化学前体物CO、SO₂、NOy和O₃浓度变化有重要影响。更多还原

【Abstract】 Based on the continuative automatic measurement data of several photochemical precursors included CO,SO₂,NOy,O₃,wind speed and wind directs made on the top floor of a seven-floor building in Sun Yat-sen University of Guangzhou during January and February 2004,combined with the surface temperature data of Guangzhou meteorological weather station and air pollution index（API） data of the same period,the influence of meteorological condition on the behavior of photochemical precursors’ concentrations was studied.It was found that cold air activity influenced on the concentrations of the photochemical precursors and O₃ in winter.更多还原
