Optimum Strategy for Siting of New Tidal Stations in the Bohai Sea

摘要

A two-dimensional tidal model with the adjoint method is used to investigate the optimum strategy for siting of new tidal stations in the Bohai Sea. Open boundary conditions of the model are estimated and the M2 constituent in the Bohai Sea is simulated by assimilating observations from tidal stations and T/P altimeter. Harmonic constants (HCs) at grids on the coastline computed by assimilating real observations serve as observed values for subsequent experiments, in which HCs at grids on the coastline are estimated by assimilating observed values of all tidal stations with different strategies. By analyzing the mean vector difference (MVD) between HCs' observed and inverted values on the coastline, the optimum strategy for siting of new tidal stations was obtained. To investigate the influence of uniform and nonuniform siting, experiments with different principle are carried out. Results indicate that the uniform siting is more effective than nonuniform siting.
