Process Analysis of Ozone Formation in the Yangtze River Delta

  • 摘要: 建立了二维空气质量模式模拟长江三角洲地区臭氧体积分数,模拟结果和实测值吻合较好.并以常熟地区为例分析了臭氧生成过程.结果表明:干沉降对大气臭氧有明显的去除作用,平均为2.1 μL/(m3·h);水平输送过程对臭氧的影响和化学臭氧生成速率P(O3)具有明显的日变化特征;总体来说,水平输送对臭氧有净的去除,平均为1.9 μL/(m3·h);化学生成过程则增加臭氧体积分数,净生成速率为5.3 μL/(m3·h),表明该地区大气有较强的氧化性;计算了该地区的臭氧生成效率,结果表明1分子NOx从排放到去除期间可以生成7.5分子O3.
