三维正压非线性潮汐潮流伴随同化I：数值建模

Based on the simulation of M2 tide and tidal current in the Bohai and Yellow Seas, twin experiments are carried out to invert the prescribed distributions of open boundary conditions in order to validate the three-dimensional numerical barotropic adjoint tidal model. The inversion has obtained satisfying results and the prescribed distributions have been successfully inverted, which demonstrates the strong ability of the adjoint model. In order to research the ill-posedness of parameter estimation inverse problems, the experiments also discuss the influences of parameter distributions, initial guesses, model errors and data number on the inversion of open boundary conditions.
