赤道重力陷波在近赤道区海流运动中的作用THE ROLE OF THE EQUATORIAL TRAP WAVE IN EQUATORIAL CURRENT MOVEMENT

摘要(Abstract)：
对小风天气条件下表层海流观测资料进行能谱密度分析,指出:东分量海流具有很明显的0.51d、3.9d和7.7d周期。0.51d是半日潮周期,即12h25min的周期;3.9d周期恰与赤道重力陷波n=2相对应,这是南纬3°～4°范围内一个重要波动;7.7d则是大小潮周期。而在北分量海流能谱中,则只有潮流0.51d和7.7d周期,3.9d周期消失,它进一步说明陷波的特征。此外,还用7m和40m层流资料与表层流进行对比,两者变化规律基本一致。
