  • The vertical salinity structure in the Hohai Sea and the Huanghai Sea have typical self-similar charotters.However.horizontal salinity distribution is influenced by advection,horizontal diffusion,river discharge,etc.By using observed sea salinity data,a similarity function of vertical salinity profiles of the Bohai Sea and the Huanghai Sea has been constructed.0a the basis of vertical integrated equations of motion and equation of continuity,and governing equations about the distribution of 3 characteristic factors (surface salinity Ss,bottom salinity SH,and thickness of upper homogeneous layer h),and combined with the similarity function,a quasi-threedimensional numerical model of salinity structure has been developed.In the model,the comprehensive effects of sea surface wind stress and heat influx.advection,diffusion,entramment,bottom as well as lateral eddy mixture are taken into consideration.It is shown that the numerical model is more practical and the results of the trial prediction are satisfactory.
