Role of wind-induced current through Qiongzhou Strait in summer

Five numerical experiments are made by employing a high-resolution Princeton Ocean Model (POM) to investigate the role of wind-induced current through Qiongzhou Strait in summer. The numerical model results show that the tidal-induced residual current through Qiongzhou Strait (QS) is westward, about 15 cm/s, and the wind-induced current by summer monsoon is eastward, about 4 cm/s. The combination effect of tidal wave, surface wind stress, open boundaries also results in the westward residual current through the QS, about 6 cm/s. The tidal-induced residual current is an important mechanism to explain the westward water transport, and the wind-induced current is not significant.
