摘要：

利用有限元海洋模式ADCIRC(Advanced Circulation Model,)建立了高分辨率的渤黄海二维潮汐潮流数值模型,该模型以M2,S2,K1,O1等8个分潮的水位作为驱动,模拟出了该8个分潮的潮汐潮流调和常数;利用该调和常数预报的潮位和二维平均潮流与实测资料相比,符合较好;利用模拟得到的潮汐潮流调和常数,以Matlab为平台,建立了能独立运行的可视化潮汐潮流预报系统,该系统可以预报渤黄海任意时刻、任意地点的潮位和平均潮流,并且可以查询渤黄海任意地点的部分潮汐特征值,该系统运行快捷,使用方便,可为海上作业提供环境预报服务。

A refined twodimensional tide and tidal current model is built based on the finite element ocean model ADCIRC(Advanced Circulation Model).The model is forced by 8 tide constituents of M2,S2,K1,O1,etc,and the corresponding 8 tide harmonic constituents are calculated using the model result.The tide and tidal current forecasted by the calculated harmonic constituents agrees well with the observation.A visual tide and tidal current forecasting system which can be operated independently is established based on Matlab.The system can forecast the tide and depthintegrated tidal current in the Bohai Sea and the Yellow Sea.Some of the tide characteristics also can be shown through the system.The tide and tidal current forecasting system can be operated fast and conveniently and provide forecasting service for the offshore operation.
