利用NCEP 再分析风场驱动WAVEWATCH III 海浪模式对北太平洋海域的海浪过程进行模拟,利用浮标观测资料对模拟出的海浪要素有效波高进行验证, 发现他们之间具有很好的一致性。基于模式输出的有效波高等波浪要素, 利用特征波参数化理论, 在海洋环流模式中引入海浪搅拌混合作用,分析其对北太平洋海表面温度模拟的影响, 初步数值模拟结果表明, sbPOM 模式在考虑海浪搅拌混合作用以后, 模拟精度进一步提升, 这对提供一个准确的大气模式下边界条件具有重要作用。 |

Abstract: |
In this paper, the National Centers for Environmental Prediction reanalysis wind data was used to drive WAVEWATCH III (WW3) to simulate the process of ocean waves in the North Pacific. The simulation results, which were compared with buoy data, show that the significant wave heights from simulation and observation are remarkably consistent. Based on the simulated wave parameters, the significant wave height obtained using WW3, and the theory of the parameterization of feature waves, wave-induced mixing was introduced into the ocean circulation model and its influence on the sea surface temperature in the North Pacific was analyzed. The primary simulation results showed that by considering the wave-induced mixing in the sbPOM model, the accuracy of simulated sea surface temperature has been further improved. This plays an important role in providing accurate lower boundary conditions for atmospheric models. |
