Abstract

Abstract:

Using the observed data from a submerged buoy system at Liuhua in the northern South China Sea in April 2011, the characteristics of internal solitary waves (ISWs) have been studied by analyzing the isotherms and current fields near the thermocline. It is found that the ISWs mainly came from the strait between Luzon and Fuga islands, generated during the spring tide period, and that the propagation direction of the ISWs was 292° mostly. Most of the ISWs were Type a, appeared regularly at 0 o’clock almost everyday, and the average period was 24 hours. In addition, an ISW with the maximum amplitude during the observation was analyzed. It appeared at 1 o’clock on April 21st. It was a typical first-mode depression wave, and its amplitude, period, velocity, direction and half wave width were 80.9 m, 24 min, 1.29 m·s^-1, 298°, and 129.4 m, respectively.
