| 摘要 | Six parameterization schemes of roughness or drag coefficient are evaluated on the basis of the data from six experiments. They present great consistency with measurement when friction velocity u(*)<0.5 m/s (approximately corresponding to 10 m wind speed U-10<12 m/s) and large deviation from measurement when u(*)>= 0.5 m/s (approximately U-10 >= 12 m/s). In order to improve the deviation, a new parameterization of drag coefficient is derived on the basis of the similarity theory, Charnock relationship and Toba 3/2 power law. Wave steepness and wind-sea Reynolds number are considered in the new parameterization. Then it is tested on the basis of the measurements and shows significant improvement when u(*) >= 0.5 m/s. Its standard errors are much smaller than the ones of the other six parameterizations. However, the new parameterization still needs more tests especially for high winds.; Six parameterization schemes of roughness or drag coefficient are evaluated on the basis of the data from six experiments.
