| 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. |
