Zhang Aichen Liu Shuhua(Dept. of Geophysics , Peking University , Beijing 100871)Ye Wenhu(Research Center of Environmental Science, Peking University, Beijing 100871)  
The diffusion experiment over a low two-dimensional hill near the coast line has been shown under certain conditions, if the ratio of turbulence intensity to it's scale is not large enough between two neighboring layers, fumigation will not occur when the upward plume penetrates down into the lower layer where the strong mixing exists . It only displays a jumping of the curves of σz and σy at certain distance . The paper also introduces the results from two sets of wind tunnel experiments as comparison to demonstrate the above conclusion .
