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.
