【摘要】 文中将海洋分为具有密度阶跃的两层，设各层内各物理量与深度无关，用推广的ＡＤＩ方法进行包括潮流和风海流的二层流场计算，待流场计算稳定后，与温度扩散方程和上均匀层深度预报方程相耦合，对黄渤海区表、底层温度和上均匀层深度作了为期４ｄ的试报。然后，通过温度垂直剖面自模函数预报出三维的水温场。试报结果表明，整个模式的预报性能及试报结果与实测的吻合程度是令人满意的。更多还原

【Abstract】 In the paper, the sea is divided into two layers with density jumping, assuming that the physical parameters in each layer are independent of depth. The two-layer flow with tide and wind currents iS calculated with the extended ADI method. After the calculation for flow field is stable, coupled with temperature diffusing equations and the prediction equation of depth of upper homogeneous layer, a four-days time prediction of the surface, bottom temperature and depth of the upper homogeneous layer of the Huanghai and Bobal Seas. At the same time, a three-dimensional sea temperature field is predicted through a similarity function of vertical temperature profile. The results indicate that the prediction quality of the whole model and the fitting degree between the predicted results and measured values are satisfactory.更多还原
