摘　　要：采用二维非线性潮流数值模型计算了黄、渤海7000余计算点M2、S2、K1、O1、M4和MS4准调和分潮的17余万个潮流调和常数,依此研制开发了黄、渤海二维潮流数值预报软件,可以在船上即时预报黄、渤海任意点任意时刻的潮流。实验结果表明,潮流数值预报的精度较高,达到了实用的程度,可以较好地为航行船舶服务,保障船舶航行安全。More than 170,000 harmonic constants of tidal current of six quasi-harmonic constituents (M_2,S_2,K_1,O_1,M_4 and MS_4) at 7,000 grid point in the Yellow Sea and Bohai Sea are computed, based on the two-dimensional nonlinear tidal current numerical model. With these harmonic constants a two-dimensional tidal current numerical prediction software is developed, by which the tidal current information at any time and any position in the Yellow Sea and the Bohai Sea and be predicted on board. The test results indicate that the accuracy of prediction satisfies practival requirements and this software can be used for marine service to ensure navigation safety.
