Abstract

Abstract

Under the spherical coordinate,a new 3-D semi-implicit numerical model,considering the tide-producing potential,is developed simulate simulate M₂ tides and tidal currents in the Isohai Sea,the Huanghai Sea and the East China Sea.The conyutanonal results cointide with the observed M₂ tide in these seas.Compared with 65 gauge stations,it is slxnxm that the averaged absolute difference between the simulated and the observed amplitudes is only 6.4 cm; the averaged difference of phase-lags is 6.4°.The calculated M₂ tidal chart consists with Fang's chart(1986) which was drawn based on both numerical and observational results.Compared with 47 current station,the averaged absolute deviation between the calculated and observed harrrpnic constant,Ucosζ、Usinζ、Vcosη、Vsinη of vdal currents at different water layers are from 2.6 cm/s to 4.9 cm/s.The calculated vertical structures of tidal currents are also in fairly good agreement with the observed results.It is the first time to reveal that the current-antphidnxmc points at different layers are lcxated at the same horiwntal poition.The dissipation of M₂ tidal energy is also given.
