On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.

After that, a numerical model about Zhejiang shore tide is established by mike21 program. After validating the good agreement between simulated results and observed ones, the planar hydrodynamic flow of this ocean area is analysed in detail. Then co-tidal and co-range chart of each main tide is drew based on the computational result. It can be found that each co-tidal and co-range chart that is based on the simulated result is suitable to the co-tidal and co-range chart that is deduced from autoptical data, besides, the modle co-tidal and co-range chart can perfect the co-tidal and co-range chart from autoptical data where autoptical data is too hard to get .

Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.
对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明:1、强层化季节的陆架海水体一般呈现显著的三层热盐结构,在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层;2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制,而在潮流底边界层内,潮混合是水体热量、物质、动量与能量垂直交换的主要机制;3、潮混合影响的深度由潮流大小决定,在黄海,一般可达10-15 m,因此,在水深较深的区域,在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域,这显著抑制水体内物质的垂直通量,为物质垂直交换的瓶颈,而在水深较浅的区域,潮混合影响范围可至跃层底部,因此物质在跃层以下整个水体中混合非常均匀,当跃层内间歇性强混合发生时,可以产生显著的跨跃层物质输运;4、近底潮致强湍流耗散缓慢地向上传播,底上不同深度处垂直湍扩散系数也具有显著的位相差异,且二者均随时间呈现四分之一周日周期的变化;5、在地形较为平坦的中央海盆区,内波活动非常微弱,因此跃层内湍流混合非常弱,垂直扩散系数为分子扩散水平,跨跃层物质通量受到显著抑制,而在地形变化较为显著的局地陆坡区,内波活动非常活跃,除内潮的影响外,高频内波与内孤立波的影响也很显著,因此跃层内存在很强的间歇性强混合,内孤立波存在的区域,水体湍流混合显著增强。

With sea level rise,the partial tide amplitude will be increased,but diminish in some part area;meanwhle tide counting position of partial tide moves unceasingly to southeast direction;Tide amplitude change causing by sea level rising can be taken the Lvsi port as the boundary,to the north,partial tide amplitude enhances unceasingly,and to south it diminishes,especially in destroyed Yellow river it has less enhancement;The region where has the largest increasing partial teide amplitude also the palce which has the quickest erosion rate.sea level rising has a good relation with the beach erosion.
2海平面上升后分潮的振幅将随之而变大,但在部分区域,分潮振幅随着海平面上升而减小;无潮点相对于现有的无潮点位置均向东南方向偏移;海平面上升导致的潮差变化,大致以吕四为界,以北随着海平面上升,分潮的振幅不断增大,以南振幅减小,其中在废黄河口附近的增幅也相对较小;潮差增大幅度最大的地区刚好是岸滩侵蚀最快的地区,海平面上升与岸滩侵蚀存在很好的对应关系。
