Abstract

Proper orthogonal decomposition four-dimensional Variational (POD 4D VAR) data assimilation method is used to estimate the open boundary conditions (OBCs) with a two-dimensional (2D) M2 tide in the Bohai Sea by assimilating the TOPEX/Poseidon (T/P) altimeter data. Qian et al. [14] assume that the OBCs are temporally and spatially varying and optimize the OBCs in the Bohai, Yellow and East China Seas and in this paper we only optimize the Fourier coefficients of the OBCs. In the practical experiment, the absolute mean difference between the model results and observations are 2.8 cm and for amplitude and phase-lag, respectively, and the cochart obtained can describe the character of tide in the Bohai Sea, suggesting that the inversion of the OBCs is successful.
