Abstract
In this research the Princeton Ocean Model (POM) is used to study the sea surface elevation (SSE) during typhoon that moved over the Gulf of Thailand (GoT), covering the domain 6ฐN to 14ฐN and 99ฐE to 105ฐE. The simulation concerns a case of Typhoon Muifa which occurred during November 21-28, 2004. The model is the time-dependent, primitive equation, Cartesian coordinates in a horizontal and sigma coordinate in the vertical. The model grid has 37 ื 97 orthogonal curvilinear grid points in the horizontal, with variable spacing from 2 km near the head of the GoT to 55 km at the eastern boundary, with 10 sigma levels in the vertical conforming to realistic bottom topography. The model predicts the SSE up to 10.65 cm at Bangnara Estuary located in the south of Thailand. The sea level records of Buoy stations provided by the Marine Department and Hydrographic Department of Thailand are used as the observations in this study. The correlations between simulated SSE and observed SSE have strong positive correlations over the totally buoy stations of the GoT. Therefore the POM model is suitable to use to find the tendency of SSE in the GoT. From testing hypothesis, the research result meets that at the same position and same time the simulated SSE had a difference from the observed sea level not exceed RMSE at 0.05 significant levels.
