| 摘 要： | 采用功率谱分析、调和分析等方法，对南海北部－观测点连续９ｄ（１９８８年５月８—１６日）的温度。盐度和海流及跨越该期间较长的（１９８８年４月２４日－７月２２日）潮位资料进行了分析研究。结果表明，观测点存在着一种内潮现象，其波动的周期在２４ｈ左右，它传播的方向大体是偏北。

| Abstract: | he consecutive station data of temperature, salinity and currents of May 1988 and the tidal observations from April to July 1988 collected in the north part of South China Sea have been analysed by means of power spectra, harmonic analysis and other methods. The results show that the existence of internal tidal action is evident at the observation point. Mainly caused by the influence of diurnal tidal constituent, it has the characteristics of diurnal internal tide, a period of about 24 hours, and a propagation direction to the north in general. |
