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.

基于塔的气海动量通量观测：陆上和海上风能的比较

我们使用基于塔的直接测量方法研究海洋大气边界层中的海气动量通量。首先，我们将收集的数据与以前的观察结果进行比较，结果大致一致。接下来，在中低风中，陆上和海上风之间的交换系数（或阻力系数）发生偏差，这显示了面波对动量通量的影响。此外，我们使用涉及表面波的参数化方案来解释动量通量对表面波的依赖性。结果一方面巩固了表面波对动量通量的影响，另一方面验证了涉及表面波的参数化方案。
