引入表面波诱导的垂直混合来修正K廓线参数化（KPP）方案。通过四个试验个例检验了这种改进的KPP方案对一个准全球海洋环流模式的影响。为了评估模拟的上层温度和表面混合层深度（MLD），将温度和MLD的模式季节循环与Levitus气候学的结果进行比较。在这项研究中，MLD被定义为温度从10 m的参考深度变化0.8°C的深度。统计分析表明，增加波致垂直混合的测试用例可以减小上层温度的均方根差，并增加与Levitus气候学的相关性。在与Levitus气候学比较的基础上，表面波引起的混合改善了两半球夏季MLD的模拟。比较不同季节的MLD，夏季波致混合对两半球MLD的改善作用大于其他季节。模拟结果对波浪诱导混合的加权系数敏感，表明在修改的KPP方案中，优选的加权系数在0.1和0.3之间。
Surface‐wave‐induced vertical mixing is incorporated to modify the K profile parameterization (KPP) scheme. The effects of this modified KPP scheme on a quasi‐global oceanic general circulation model are examined by carrying out four test cases. To evaluate simulated upper layer temperature and surface mixed‐layer depth (MLD), the model seasonal cycle of temperature and MLD are compared with those from Levitus climatology. In this study, the MLD is defined as the depth that the temperature has changed 0.8°C from the reference depth of 10 m. Statistic analysis shows that test cases with the addition of wave‐induced vertical mixing can reduce the root‐mean‐square difference of upper layer temperature and increase the correlation with Levitus climatology. On the basis of the comparison with Levitus climatology, the surface‐wave‐induced mixing improves the simulation of MLD in summertime for both hemispheres. Comparing the MLD in different seasons, the wave‐induced mixing improves MLD in both hemispheres in summer more than in other seasons. The simulation results are sensitive to weighting coefficients of the wave‐induced mixing, suggesting that a preferred weighting coefficient be between 0.1 and 0.3 in the modified KPP scheme.
