Numerical study of M2 tide on the Gulf of Thailand

According to the previous study, M2 from SCS amplified around the coastal region but almost low in the Gulf of Thailand (hereafter GoT). To detect the M2 at the shallow part of GoT, we used the 2D numerical model simulation. The model was driven by M2 amplitude and phase from a high-resolution spatial data provided by the Geospatial Indonesia Agency. M2 model was well verified with the recent studies and assimilation data. We showed the amphridomic point around southeastern of GoT around 103.5 E and 8.5-8.6 N. The amphridomic point has clockwise direction. We also showed a virtual amphridomic point at the east of GoT (100 E and 11.5-12 N). The M2 amplitude was highest in the Bangkok Bay. The study showed an important of the high-resolution model simulation on the GoT tides.
