使用新一代大气化学传输模式WRF—Chem，模拟了黄山地区2008年4月26日和5月2日不同天气背景下污染气体的输送过程。结果表明：晴天条件下，污染气体的垂直输送主要是通过山谷风环流，将山底污染物垂直向山顶输送，黄山周边地区输送对光明顶污染物体积分数影响较小，气溶胶粒子的主要来源是新粒子生成；云雾天气下，污染物的垂直输送主要是通过边界层内的湍流扩散，夜间近距离输送对光明顶污染物体积分数贡献较大，气溶胶粒子的主要来源是地面输送。

The transport process of pollution gases under different weather situation are simulated at Mountain Huang on 26 April and 2 May 2008 by using a new generation atmospheric chemistry transfer model WRFChem. Results show that, in sunny conditions, the pollution gases are transported vertically from downhill to uphill by mountainvalley breeze circulation, the transport of pollutants in the sur rounding areas has less effect on the volume fraction of pollutants at Guangmingding, and new particle formation is the main source of atmospheric aerosols. However, in cloudy conditions, the pollution gases are transported vertically to the uphill by turbulent diffusion in boundary layer, the short range transport has much effect on the volume fraction of pollutants at Guangmingding in the nighttime, and the aerosol particles mainly come from the ground transport.
