Abstract. The Gulf of Thailand is dominated by diurnal tides, which indicates that the resonant period of the gulf is potentially close to one day. However, when applied to the gulf, the classic quarter wavelength resonant theory fails to give a diurnal resonant period. In this study, we first perform a series of numerical experiments showing that the resonant period of the gulf is approximately one day and that the resonance of the South China Sea body has a critical impact on the resonance of the gulf. In contrast, the resonance of the Gulf of Thailand has little influence on the resonance of the South China Sea body. An idealised two-channel model that can reasonably explain the dynamics of the tidal resonance in the Gulf of Thailand is then established in this study.
