Summary

The magnitude and diurnal change of turbulent bulk drag coefficients over land have been analysed using mean velocity and temperature gradient data of the planetary boundary layer. The turbulent drag coefficients can be about an order of magnitude larger over the rough land surface than over the sea surface. We computed these coefficients by the same method for three typical underlying surfaces represented by urban, grassland and Gobi desert. The results show that there are significant differences in the turbulent transfer among the three typical underlying surfaces.
