| 摘 要： | 结合南沙群岛海域出现的内潮现象 ,利用一个两层数值模式 ,通过数值试验来探讨潮汐性质、水体的层结程度、跃层所在的深度、风应力等因子对陆架坡折处内潮特性的影响 ,结果表明 :内潮的波动周期只与海区的潮汐性质有关 ;风应力、非线性效应以及正压潮源地的深度等都可改变内潮的波动振幅 ;内潮的波动振幅随海区的水体层结程度及温跃层所在的深度不同而改变

| Abstract: | Combined with the hydrologic background of the internal tide phenomenon in the Nansha Islands sea areas,a two layer model is used to numerically study the influence of tide nature,stratification degree of water,thermocline depth,wind stress etc.on the characteristics of the internal tide in the shelf slope break.It is shown that the period of the internal tide deals only with the tide nature in the sea area; wind stress, nonlinear effect and the source depth of barotropic tide may change the amplitude of the internal tide;the amplitude of the internal tide varies with the stratified degree of water and the depth of thermocline in the sea area. |
