The Surface Current of Andaman Sea Around Phuket Island and Rawe Island

บทคัดย่อ

The surface current of Andaman Sea around Phuket Island and Rawe Island were effected by tide, wind, topography site and North equatorial current. The period of tide was about 12 hours. During April to July,1997, the average surface current of Phuket buoy and Rawe buoy were 19 and 20 cm/sec, respectively. The averaged surface current in North-South component and East-West component of Phuket and Rawe buoy were 0.2 cm/sec, -0.1 cm/sec, 2.0 cm/sec and 0.2 cm/sec, respectively. During this time, the direction of surface current of Phuket and Rawe buoy were on North flow about 340° and 5° from North. Phase of velocity in East-West component was faster than phase of tide about 80°-120° or 5-8 hours. Phase of velocity in North-South component was faster than phase of tide about 30°-45° or 2-3 hours.
