Distribution of 9 Principal Tidal Constituents and Tide Prediction for the East China Sea

Abstract

By use of the hydrodynamic model, the harmonic constants of 8 principal tidal constituents (Q1, O1, P1, K1, N2, M2, S2 and K2) are obtained for the East China Sea, and the harmonic constant of Sa is calculated by two-dimensional interpolation. The calculated results agree well with the observed data around the sea. The harmonic constants can be used to predict the tide in the East China Sea. The cotidal charts of the 9 tidal constituents reveal their distribution.
