The ocean loadin characteristics are studied systematically by usin lobal and local ocean models as well as tidal au e data, the suitability of lobal ocean models is also studied. The numerical results show that the ocean models in diurnal band are more stable than those in semidiurnal band, and the correction of the chan e in tidal hei ht plays a si nificant role in deter
