| 摘 要： | 通过对四种参数化方法的比较,认为风海雷诺数RB较风速、波龄和波陡能更好地描述拖曳系数CDN。利用分组平均法对CDN与RB关系进行处理,得到最佳的CDN参数化方案。利用COARE3算法测试了四种依赖海况的粗糙长度,与实测结果进行了比较,结果表明CDN与RB的关系式更真实地反映了海-气界面动量交换过程。

| Abstract: | By analysis of the observed data, it is shown that the windsea Reynolds number RB is the best parameter to describe the drag coefficient compared with wind speed, wave age and wave slope. A relationship between CDN and RB is obtained by the bin-averaging method in order to eliminate the self-correlation effect. Integrated into COARE3 algorithm, the results show that the relationship between CDN and RB can effectually depict the momentum exchange process at the air-sea interface. |
