An Approach to the Features of Surface Layer in Liaodong Gulf
辽东湾东海岸近地层特性探讨

The surface roughness, drag coefficient and wind index are calculated with the data obtained from tower-based sensors located about 800 m from the coast. The results show that the roughness can be 0 18 m in the on-shore wind, while it is smaller in the off-shore wind; the drag coefficient can be 0 025 in the on-shore wind, while it is smaller in the off-shore wind. In addition, under the same stability, wind index decreases with the wind speed.
