%X The data from 17 wind towers in Gansu corridor have been utilized to calculate the underlying surface roughness near these wind towers,which have been compared with the roughness used in meso-scale numerical models. The results show that there are some differences between both of them,and the definition in the models can not accurately reflect the roughness and nonuniformity of real underlying surface. The difference between them increases with the vegetation complex degree of underlying surface,and peaks i...
