| 摘 要： | 无论潮流矢量是反时针旋转(f>0)还是顺时针旋转(f<0),全日潮谱峰都高于半日潮谱峰。2个半日潮周期分别为12、12.4h;2个日潮周期分别为23.9和25.8h;在半日潮和全日潮分量中,反时针分量是主要的:顺时针的半日潮能谱只有反时针的84%;顺时针的日潮能谱只有反时针的65%;浅水分潮6.2、8h和超过24h的3、4.2和5.5d等也有明显表现,但是都未通过显著性检验;夏季余流流速在5～10cm/s范围内变化,方向以南偏西为主。造成这种现象的首要的因素是夏季琼州海峡水交换基本态势和三塘附近海底地形,风对流向变化也有重要影响。 |

| Abstract: | No matter anticlockwise(f>0) or clockwise rotation(f<0) of tidal current vectors,diurnal tidal spectrum peak is higher than the semidiurnal tidal spectrum peak.The main cycles of semidiurnal tide are 12.0 and 12.4 hours.The main cycles of diurnal tide are 23.9 and 25.8 hours respectively;In the component of diurnal and semidiurnal tide,the anti-clockwise component is the main component: clockwise semidiurnal tidal energy spectrum is only 84% of the anti-clockwise semidiurnal tidal energy spectrum;clockwise ... |
