| 摘 要： | 本文使用塔基直接观测法研究海洋大气边界层中的海-气界面动量通量。首先，我们收集数据并和前人观测结果比对，其比对结果符合一致。其次，在低风速至中等风速条件下，我们发现海-气界面动量通量的交换系数（又称拖曳系数）对于向岸风和离岸风两种情形有所差异。为此，我们使用一个考虑表面波的参数化方案解释海-气界面动量通量对于表面波的依赖关系。这些结果一方面证实表面波对于海-气界面动量通量的影响，另一方面验证一个考虑表面波参数化方案的有效性。

| Abstract: | We investigate the air-sea momentum flux in the marine atmospheric boundary layer using a tower-based direct measurement method. First, we compare the collected data with previous observations, and the results are roughly consistent. Next, in the low-to-moderate winds, the exchange coefficients (or drag coefficients) deviate between onshore and offshore winds, which exhibits the influence of surface wave on the momentum flux. Furthermore, we use a surface-wave-involved parameterization scheme to explain the dependence of momentum flux on surface wave. The results consolidate the influence of surface wave on momentum flux on the one hand, and validate the surface-wave-involved parameterization scheme on the other hand. |
