Latest Advances of Global Ocean Tide Models and Their Accuracy Comparisons in Coastal Areas of China
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.
