The reliability of a numerical tide model for detiding acoustic Doppler current profiler (ADCP) data is examined on the East China Sea shelf. The process is adopted for the ADCP data obtained on 12–13 May 2003. The ocean model accompanied by the most precise harmonic constants available to public is used to compute external tides. The root mean square difference is less than 10 cm/s between the detided currents and those using the least squares method, and so the detiding process using the numerical model is available to detect the East China Sea shelf circulation faster than this speed.  相似文献

针对TOPEX／POSEIDON卫星高度计资料中的潮汐高频混淆现象，采用潮汐调和分析方法，通过比较卫星上、下行轨道交叉点两组资料分析的分潮振幅和分离潮汐后的海面高度；同时比较潮位站实测资料与遥感资料分析的分潮振幅，结果表明：采用潮汐调和分析可以有效地分离高度计资料中的潮汐信息。  相似文献
