The heavy fogs restrain the verticaldiffusion of surface layer pollutant and get tough city...
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。

Dynamic equations are used in which the vertical gradient and verticaldiffusion are parameterized.
利用动力学方程组，并对其中垂直梯度项和垂直扩散项进行了参数化处理。
3
The sensitivity of the model to various values of the stratification parameters that influence verticaldiffusion has been studied and some preliminary results presented.
