In order to provide a suitable means for the tidal prediction of the Changjiang Estuary and its adjacent area and for the open boundary conditions of tidal flow numerical model of the Changjiang Estuary, accuracy of NAO.99Jb was evaluated. The feasibility of providing open boundary conditions for tidal flow numerical model of the Changjiang Estuary was studied. The results show that the NAO.99Jb model can accurately simulate the propagation of the tide outside the Changjiang Estuary and its adjacent area; The NAO.99Jb has good accuracy outside the Changjiang Estuary, but has lower accuracy inside the Changjiang Estuary; It is feasible for using the tidal level predicted by NAO.99Jb as the open boundary condition of the tidal flow numerical model of the Changjiang Estuary, and the accuracy is good, which can be further popularized and applied.

为给长江口及邻近海域潮汐预报和长江口潮流数学模型外海开边界条件的给定提供有效手段,评估了NAO.99Jb模式在长江口及邻近海域的精度,研究了其为长江口潮流数学模型提供外海开边界条件的可行性。结果表明,NAO.99Jb模式能够准确模拟各主要分潮在长江口及邻近海域的传播;在长江口口外海域该模式潮位模拟精度较高,在长江口口内水域则精度较低;利用该模式预报的长江口外海潮位可以作为长江口潮流数学模型的开边界条件,且精度良好,该手段可进一步推广应用。

为给长江口及邻近海域潮汐预报和长江口潮流数学模型外海开边界条件的给定提供有效手段,评估了NAO.99Jb模式在长江口及邻近海域的精度,研究了其为长江口潮流数学模型提供外海开边界条件的可行性。结果表明,NAO.99Jb模式能够准确模拟各主要分潮在长江口及邻近海域的传播;在长江口口外海域该模式潮位模拟精度较高,在长江口口内水域则精度较低;利用该模式预报的长江口外海潮位可以作为长江口潮流数学模型的开边界条件,且精度良好,该手段可进一步推广应用。

In order to provide a suitable means for the tidal prediction of the Changjiang Estuary and its adjacent area and for the open boundary conditions of tidal flow numerical model of the Changjiang Estuary, accuracy of NAO.99Jb was evaluated. The feasibility of providing open boundary conditions for tidal flow numerical model of the Changjiang Estuary was studied. The results show that the NAO.99Jb model can accurately simulate the propagation of the tide outside the Changjiang Estuary and its adjacent area; The NAO.99Jb has good accuracy outside the Changjiang Estuary, but has lower accuracy inside the Changjiang Estuary; It is feasible for using the tidal level predicted by NAO.99Jb as the open boundary condition of the tidal flow numerical model of the Changjiang Estuary, and the accuracy is good, which can be further popularized and applied.
