Abstract
The dynamic of circulation patterns in Terengganu waters largely dominated
by wind forcing specifially the monsoon wind. In order to understand this dynamic, a
hydrodynamic model is applied to simulate the major circulation patterns in Terengganu
waters. The model used is a three-dimensional simulation MIKE 3 Flow Model FM by
Danish Hydrological Institute (DHI). The model exhibit that the current flwed in the
same direction with prevailing monsoon winds. While the current speed was dominated
by magnitude of monsoon winds. The maximum current speed recorded during SW
monsoon was 0.327 m/s and 0.478 m/s during NE monsoon. Additionally, the model
was able to capture the convergence and divergence current patterns during SW and
NE monsoon seasons respectively. This convergence and divergence current features
occurred at 5.5 oN to 6oN latitude off the Terengganu waters. The convergence–divergence
current pattern was suggested due to monsoon winds and effect from circulation in Gulf
of Thailand. The study fialize the variability and dynamic of current circulation patterns
in Terengganu waters are largely inflenced by monsoon winds and effect from the Gulf
of Thailand circulation.
