ABSTRACT
The South China Sea (SCS) circulation in
its southern region in the area between Peninsular Malaysia and East Malaysia
was studied from the OCCAM (Ocean Circulation and Climate Advanced Modelling).
This research aimed to illustrate the general overview of the seasonal surface
current circulation and the surface temperature profile which are lacking in
the region. The current along the Malaysia coast flows northward in the southwest monsoon and move in opposite
direction in northeast monsoon with the maximum speed of 0.4 m/s and 1 m/s,
respectively. While the current basins nearly 3°C. The study manages to analyse
the importance of the monsoonal system on the region circulation and
temperature distribution.
Keywords:
Current circulation; ocean model; sea surface temperature; South China Sea
ABSTRAK
Peredaran arus di
bahagian selatan Laut China Selatan (LCS) di antara Semenanjung Malaysia dan
Malaysia Timur dikaji melalui OCCAM (Ocean Circulation and Climate Advanced
Modelling). Kajian ini bertujuan untuk memberi gambaran secara umum peredaran
arus permukaan dan suhu permukaan laut mengikut musin yang amat kurang difahami
di kawasan ini. Arus di sepanjang pantai timur Semenanjung Malaysia
bergerak menuju utara semasa musim monsoon barat daya dengan kelajuan maksimum
mencecah 0.4 m/s. Manakala semasa monsun timur laut arus menuju arah berlawanan
iaitu ke arah selatan dengan kelajuan maksimum mencecah 1 m/s. Semasa arus
bergerak menuju selatan,air bersuhu rendah dibawa dari
bahagian utara yang menyebabkan bahagian tengah LCS mengalami penurunan suhu
sebanyak 3oC. Secara keseluruhan kajian ini mampu
membuat analisis kepentingan monsun terhadap perubahan sistem melibatkan
pergerakan arus dan perubahan suhu permukaan laut.
Kata kunci:
Laut China Selatan; pemodelan laut; peredaran arus; suhu permukaan laut
