| 摘 要： | 本文基于FVCOM(Finite-Volume Coastal Ocean Model)模式,模拟了泰国湾及其周边海域K1、O1、M2和S2四个主要分潮。采用47个验潮站实测调和常数与模拟结果进行比较,所得4个分潮的均方差分别为4.06cm、3.76cm、8.22cm和4.71cm,符合良好。根据计算结果分析了泰国湾及其周边海域的潮汐、潮流的分布特征和潮波的传播特征。数值试验表明,现有的数字水深资料(ETOPO1,ETOPO5,DBDB-V)的准确度不足以合理地模拟泰国湾潮波。

| Abstract: | The principal tidal constituents K1,O1,M2 and S2,in the Gulf of Thailand are numerically simulated using the FVCOM ocean model. The model results are compared with observations at 47 tide gauge stations,which show a satisfactory agreement. The root-mean-square differences between the simulated and observed harmonics are 4.06 cm,3.76 cm,8.22 cm and 4.71 cm respectively. Based on the model results,distributions of tides,tidal current ellipses,tidal residual currents and tidal energy flux density vectors of K1,O1,M2 and S2 constituents are presented. Numerical experiments show that the accuracy of the existing digital bathymetry data (ETOPO1,ETOPO5,DBDB-V) is inadequate for a reasonable simulation of the tides in the Gulf of Thailand. |
