摘　　要：利用伴随同化法得到的开边界和底摩擦数据,数值模拟了渤黄东海的M2分潮。计算出M2分潮调和常数的模拟值与实测值之差的绝对平均值:振幅差为3.46cm,迟角差为3.89°。得到M2分潮的潮汐潮流等结果,较好地反映了东中国海M2分潮的特征。The open boundaries and the bottom friction coefficients obtained by adjoint method were used in the Mtide modal in the Bohai Sea, the Huanghai Sea and the East China Sea. The mean absolute differ- ences between the simulated and the observed were computed. The mean absolute difference of the amplitude is 3.46 cm, and the mean absolute difference of the phase-lag is 3.89°. Based on the computational results, the Mtide cotidal chart and ellipticity and rotating direction of current vector chart was mapped out. These results reflected the characteristics of the Mtide very well.
