| 摘 要： | 对TOPEX/Poseidon(以下简称T/P)高度计资料直接分析得到4个主要分潮(M2,K1,S2和O1)的调和常数,并与5个全球大洋潮波模式的模拟结果和138个验潮站观测资料的分析结果进行了系统比较,得出如下结论:在深水大洋,高度计资料直接分析结果与潮波模式模拟结果较一致;模拟出的无潮点的个数和位置也较一致;半日分潮模拟结果比全日分潮要好。5个模式模拟结果之间的差异相对较小,振幅的绝对偏差在1.0 cm左右,迟角的绝对偏差在10(°)左右。在陆架浅海,不同模型结果差异相对较大。高度计资料直接分析结果比模式模拟结果普遍偏小,尤其在陆架浅海更是如此。

| Abstract: | The harmonic constants of the four dominant constituents M_2,K_1,S_2 and O2 obtained from the analysis of TOPEX/Poseidon altimeter data are compared with the simulation results of 5 global ocean tide models and observation of tide gauge and it is suggested that result of data analysis agrees well with that of model simulation in the area far away from the coast,both in the number and the position of amphidromic points,and the result of semidiurnal constituents is superior than diurnal ones.Difference between the simulation results of each 2 of the 5 global ocean tide model is relatively small with the absolute difference of amplitude less than 1.0 cm and phase lag less than 10 degrees.In the area of continent shelf,result of model simulation can differs a lot from one to another.Totally,value of the harmonic constants from T/P data analysis is smaller than the result from model simulation especially on the continent shelf. |
