| 摘 要： | 介绍TPXO、FES、Chinatide、MIKE Global Tide、Utide等典型海潮模型，总结归纳其同化潮汐数据来源和最新的海洋地形数据，利用我国沿岸长期验潮站以外的26个中短期潮位观测站评估TPXO等海潮模型预报精度。结果表明，全球海潮模型对我国沿海M2分潮的预报精度普遍较低，且主导了几种海潮模型在中国海域的整体预报精度；相比MIKE Global Tide和TPXO7.2,TPXO8、TPXO_Yellow Sea 2010和TPXO_China&Ind模型在我国沿海的预报精度更高。

| Abstract: | A series of representative new global ocean models(TPXO, FES2014, MIKE Global Tide, Chinatide, et al.) are reviewed. Meantime, the available multi-sourced global tidal data and the latest international ocean topographic datasets are also summarized. The harmonic constituents of 26 short/middle-term tidal gauge stations along Chinese coastline are used to estimate the accuracy of 6 global ocean tide models. The comparison of RSSs formed by 8 principal constituents shows that the prediction accuracies of M2 constituents given by different GOMs are generally low in China sea, and the M2’s prediction error contributes 70%~90% of the overall accuracy. In contrast to MIKE Global Tide and TPXO7.2, the performance of TPX08, TPXO_Yellow Sea 2010 and TPXO_China&Ind are better in China coastal area. |
