【摘要】：Stokes漂流对上层海洋温度场具有不可忽视的影响,基于WAVEWATCH III海浪模式模拟结果计算出Stokes漂流流速,将其引入到SBPOM模式的动量方程中以探究Stokes漂流对海表面温度的影响。结果表明,模拟有效波高与实测值保持较好的一致性,平均相关系数最大为0.88。北太平洋Stokes漂流的分布呈现出高纬度较大的带状特征,最大流速可达0.2 m/s。Stokes漂流对北太平洋海表面温度的影响在-2~1℃之间,高纬Stokes漂流影响作用大于低纬,其中太平洋西北海域影响最大,可达-2℃,赤道影响最小。通过Argo浮标资料验证,考虑Stokes漂流模拟的海表面温度更趋近于实测值,说明在海表面温度计算中,考虑Stokes漂流是必要的。
[Abstract]:The effect of Stokes drift on the upper ocean temperature field can not be neglected. Based on the simulation results of WAVEWATCH III wave model, the velocity of Stokes drift is calculated and introduced into the momentum equation of SBPOM model to explore the effect of Stokes drift on sea surface temperature. The results show that the simulated effective wave height is in good agreement with the measured value, and the maximum correlation coefficient is 0.88. The distribution of Stokes drift in the North Pacific presents a large zonal feature at high latitudes. The influence of the maximum velocity of 0.2 m/s.Stokes drift on the sea surface temperature of the North Pacific Ocean is between-2 and 1 鈩，
