Preliminary analysis of tide simulation of the East China Sea of the Global FVCOM model

Abstract:

This study is aimed at validating the Global Finite Volume Community Ocean Model (Global FVCOM) for tidal simulation in the East China Sea (ECS) (24°N to 41°N and 118°E to 132° E). The model data comparisons were made for the amplitude and phase lag of M₂, S₂, K₁ and O₁ at 99 observations along the coast of the ECS. Generally, the model results agreed well with observations, except for areas where the resolution of grid does not resolve the local bathymetry well. The amplitude and phase lag root mean square errors are 15 cm and 10° for M₂ tide and 8.2 cm and 9° for K₁ tides. The results of Global FVCOM provide a foundation for further development on establishing a multi scale global regional ocean model for the ECS research.
