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M_2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。
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.
