Abstract
Many observations show that in the Yellow Sea internal tidal waves possess the marked characteristics of internal Kelvin wave,and in the south of the Yellow Sea the nonlinear evolution of internal tidal wave is one of mechanisms producing internal solitary waves.In this paper,the model of internal Kelvin wave for continuous stratified ocean is given,and an elementary numerical study of this model is made in the South Yellow Sea.The simulated results indicate that the large vertical shear(absolute value) of horizontal velocity u of the particle by internal tide takes place within the layer with depth less than 30 m,and the vertical shear is very small within the layer with depth larger than 30 m.
