摘要： 极地潮汐对海冰动力学和漂浮冰架的研究起着重要的作用。现有的海洋潮汐模型在浅海和极地海域的精度远低于开阔深海海域。本文总结了全球潮汐模型在南极海域的研究进展, 环南极海域潮汐模型的构建方法以及南极半岛(Antarctic Peninsula)、罗斯海(Ross Sea)海域、龙尼-菲尔希纳冰架(Filchner-Ronne Ice Shelf, FRIS)、威德尔海(Weddell Sea)海域、埃默里冰架(Amery Ice Shelf, AIS)5个典型区域的潮汐模型构建方法。评价了FES2014、TPXO9、CATS2008以及区域潮汐模型在南极海域的精度以及在南极半岛、罗斯海海域、威德尔海海域、埃默里冰架4个典型区域的精度。FES2014和AntPen模型在南极半岛区域模型精度较高, 和方根误差(Root Sum Squares, RSS)分别为8.61 cm和7.46 cm。TPXO9和RIS_Optimal模型在罗斯海海域精度较高, RSS分别为5.62 cm和6.21 cm, TPXO9模型在威德尔海海域以及埃默里冰架精度最高, RSS分别为18.33 cm和12.77 cm。

Abstract: Polar tides play an important role in the dynamics of sea ice and floating ice shelves. Currently, the accuracy of ocean tide models is much lower for shallow and polar seas than for open deep seas. This paper summarizes the latest research findings from the application of global tide models to the Antarctic region, and the development of tide models for five Antarctic regions, including the Antarctic Peninsula, Ross Sea, Filchner–Ronne Ice Shelf, Weddell Sea, and Amery Ice Shelf. The accuracy of the FES2014, TPXO9, CATS2008, regional tide models and tide models for the Antarctic Peninsula, Ross Sea, Weddell Sea, and Amery Ice Shelf were evaluated. Accuracy of FES2014 and AntPen are higher in the Antarctic Peninsula region. The Root Sum Squares (RSS) are 8.61 and 7.46 cm, respectively. Accuracy of TPXO9 and RIS_Optimal are higher in the Ross Sea area, with RSS of 5.62 and 6.21 cm, respectively. Accuracy of TPXO9 is highest in the Weddell Sea and Amery Ice Shelf areas, with RSS of 18.33 and 12.77 cm, respectively.
