boundary layer diffusion

基本解释

In a fully developed convective boundary layer, the variation of vertical diffusion coefficients increases with height.
在充分发展的对流边界层中，垂直扩散系数随高度的增加而加大。
This impervious layer or boundary will retard the free diffusion of moisture. This condition is referred to as case hardening.
这一不透气的壳层(或边界层)会阻滞水分自由扩散，这种情形称为表面硬化。
Therefore, in the convective boundary layer the variation of vertical diffusion coefficients obtained from the Doppler acoustic radar can express the diffusion process well.
用声雷达测量的垂直扩散系数能够较好地反映对流边界层中的扩散过程。
