中文摘要：

阐述潮汐分析方法和建模方法，归纳总结了FES，CSR，GOT，NAO，TPXO，EOT，DTU，HAMTIDE及OSU系列全球海潮模型的建立机构、使用数据及构建方法等。对比分析2010年后出现的几种新的海潮模型（FES2012，EOTlla，DTUIO和HAMTIDElla）在南大洋的M2振幅，发现模型间差异主要集中在浅水及极地地区，其中极地地区高精度卫星测高数据的缺少及海冰的季节性变化，是导致建模精度较差的主要原因。最后对海潮模型的发展方向提出一些建议。

英文摘要：

The theories of tidal analysis and methods of ocean tide modeling are presented at first, and a series of global ocean tide models （ FES, CSR, GOT, NAO,TPXO, EOT, DTU, HAMTIDE and OSU） are summarized, in- cluding their affiliations, data, and methods of modeling. The amplitude differences of M2 constituent of four new models （FES2012, EOT1 la, DTU10, HAMTIDE11 a） which released after 2010 are provided to show that shallow- water and polar sea are the main different regions. The main reasons leading to a poor accuracy in polar sea tidal modeling are the lack of highly accurate altimetry data and the presence of sea ices. Some suggestions are proposed for the future study of ocean tide modeling.
