摘要
利用实验室和有代表性的外海观测数据综合分析表明,海面粗糙度对波龄的依赖性与是否将实验室和外海数据一起考虑有关,而风应力拖曳系数与此无关,且随波龄增大而减小。利用Toba-3/2指数律和风浪成长关系的分析表明,风应力拖曳系数为常数或随波龄的增大而增大,与上述结果定性上相矛盾,说明风浪对风应力拖曳系数影响问题需要进一步研究。
In order to investigate the wind wave effect on momentum flux through air-sea interface, laboratory experimental data and representative field data are analyzed together. It is shown that the qualitative depen- dence of sea surface roughness length on wave age is sensitive to whether the laboratory and field data are taken into account together or not. The wind stress drag coefficient is a robust parameter, and it decreases with increasing wave age based on the observational data. On the other hand, when drag coefficient is derived from the combination of Toba-3/2 power law and fetch-limited relationships of wind waves as well as 3/5 power law, it is a constant or increases with wave age, which is contradicted with the former result. It is clear that the influence of wind wave on drag coefficient is still remained unsolved.
