Abstract

Abstract

By means of three-dimensional baroclinic primitive equation model——Hamburg shelf ocean model (HAMSOM),the tide and tidal currents in the seas adjacent to Zhejiang are simulated.Furthermore,the original model is improved by two numerical technologies——nested grid and moving boundary method,which are introduced to increase the computational precision.The improved mode is proved to be successful while it is applied to the seas adjacent to Zhejiang.Comparing the computed values with those of 50 tidal observatories,it is found that the computational precision with fine grids and moving boundary is generally higher than that with coarse grids or fixed boundary.The root-mean-square values of comparative results show that the difference between the simulated and the observed amplitudes of M₂ constituent is only 4.6 cm,the difference of phase-lags is 7.14°;the difference of amplitudes and phase-lags of S₂ constituent are 5.0 cm and 5.4°;the difference of amplitudes and phas-elags of K₁ constituent are 2.25 cm and 5.76°;the difference of amplitudes and phase-lags of O₁ constituent are 1.56 cm and 5.5°.
