ABSTRACT: This paper explores the
dynamic of meteorological forcing on current circulation pattern in the
vicinity of Bidong using an unstructured flexible mesh hydrodynamic model. The
forcings were wind, tides, temperature and salinity. The seasonal wind monsoon,
mixed tides with dominant diurnal and tropical monsoon climate is
characteristics of Bidong Island. We find that this area has different current
circulation patterns in response to monsoon changes. It also experienced a
small scale of island wake during NE monsoon. This island wake was generated by
a strong northeasterly wind. We performed a series of numerical simulations
based on three dominant factors in circulation, and evaluated the model using
wind, tides and density. We investigated the wind-driven circulation and
residual current. This study contributes to the debates on hydrodynamic of
current circulation in vicinity of Bidong Island. Specifically, this study was
conducted to understand the changes of currents by seasonal wind (NE monsoon
and SW monsoon), temperature and salinity.
