The roughness coefficient experiments indicate that the change in tropical cyclone intensity will be varied with different coefficient . also the experiment indicates the wind of tropical cyclone is reduced by the land and the effect of an tropical cyclone landfalling process could result in the height increasing of tropical cyclone boundary layer 通过不同的陆地粗糙度参数数值试验，结果表明，粗糙度越大，热带气旋强度减弱越多，其造成的非对称结构也越明显；而且，由于登陆作用，陆地一侧的地表风减小，登陆的摩擦作用将可能导致边界层的高度增加。
