| 摘 要： | 商丘市的大雾多形成在大陆高压型、冷锋前暖区型、均压场型、(低压)倒槽型天气形势中。空气中的污染物不仅增加了水汽凝结核,那些可溶性气溶胶还降低了饱和水汽压,使空气中的水汽更容易饱和,因此被污染的空气更容易形成雾。而大雾天气抑制了近地面层污染物的垂直扩散,加剧了城市污染。

| Abstract: | The heavy fogs of Shangqiu are formed by the weather situations: continental anticyclone,warm zone in front of cold front,uniform pressure field,and low pressure with an inverted trough.Air pollutant not only can increase water condensation nuclei,but also the soluble aerosol can decrease saturation water vapor pressure,making water vapor in the air easy to saturate.Results show that polluted air is easy to form fog.The heavy fogs restrain the vertical diffusion of surface layer pollutant and get tough city pollution. |
