烟台外海潮波的特征

在烟台外海,潮汐属于正规半日潮性质,而潮流属于日潮流性质.用数值模拟和实测潮流分析两种方法研究了该特征并解释造成这一现象的原因:在烟台外海M2分潮具有驻波振动,存在着M2分潮流的辐聚、辐散现象,因而该海域M2分潮流很小.该海域日分潮流没有辐聚、辐散现象,因而日分潮流相对较强,从而造成了该海域的潮汐、潮流性质相异的特殊现象.

Study on tidal wave properties in the marginal seas adjacent to Yantai

In the marginal seas adjacent to Yantai,tides are regular semidiurnal tides;and tidal currents are diurnal currents.In this paper,these properties have been studied and the cause of these phenomena has been explained by methods of numerical modeling and tidal current harmonic analysis.The computation indicates that standing oscillation of M_2 constituent forms in the marginal seas adjacent to Yantai.As a result,in this sea area,convergent or divergent phenomenon of the currents of M_2 constituents is produced,which make the currents of M_2 constituent very weak.On the contrary,convergent or divergent phenomenon of the currents of diurnal constituents hasn't appear,so that the currents of diurnal constituents are relatively strong.Therefore,in the marginal seas adjacent to Yantai,tides and tidal currents make up these different properties.
