由TOPEX/POSEIDON卫星高度计资料导出福建和台湾邻近海域的潮汐特征

The tide characteristics of the seas adjacent to Fujian and Taiwan derived from TOPEX/POSEIDON altimeter data

本文的目的是通过覆盖福建、台湾邻近海域TOPEX/POSEIDON(T/P)卫星高度计 5cm精度的海面高度资料来导出该海域的潮汐特征 .文中对T/P第 1 0～1 86重复周期的资料进行处理 ,用响应法对提取的潮汐高度时间序列进行分析 ,得出沿 6条地面轨道 8个主要分潮的调和常数 ,与 6个实测站位数据比较 ,M2 ,S2 ,K1,O1的矢量差均方根分别是 8 8,4 7,3 2 ,1 6cm .联合沿岸实测资料绘出 2 0°～ 2 8°N ,1 1 7°～ 1 2 4°E范围内M2 ,S2 ,K1,O1等主要分潮同潮时图和等振幅图 ,给出福建。

The aim is to derive tide characteristics of the seas adjacent to Fujian and Taiwan from the TOPEX/POSEIDON(T/P) sea surface height data of 5 cm accuracy. T/P geophysical data records of cycles 10～186 are processed and the tidal waves are analyzed by the response method. The solutions along ground track are obtained for eight major constituents (M 2,S 2,N 2,K 2,K 1,O 1,P 1 and Q 1). The comparisons of T/P tide constituents with 6 tide gauge observation indicate the vector differences rms for M 2,S...
