Abstract:

Based on MM5, POM, and WW3, a regional atmosphere-ocean-wave coupled system is developed in this work under the environment of Message Passing Interface. The coupled system is applied in a study of two typhoon processes in the South China Sea (SCS). The results show that the coupled model operates steadily and efficiently and exhibits good capability in simulating typhoon processes. It improves the simulation accuracy of the track and intensity of the typhoon. The response of ocean surface to the typhoon is remarkable, especially on the right side of the typhoon track. The sea surface temperature (SST) declines, and the ocean current and wave height are intensified. In the coupling experiment, the decline of SST intensifies and the inertial oscillation amplitude of the ocean current increases when the ocean-wave effect is considered. Therefore, the atmosphere-ocean-wave coupled system can help in the study of air-sea interaction and improve the capability of predicting and preventing weather and oceanic disasters in SCS.
