摘要： 中国南极长城站位于南极乔治王岛的菲尔德斯半岛南端, 其附近海域的潮汐观测研究对于长城站建设和维护及其海洋研究等都具有重要意义。本文基于三维水动力海洋数值模型(FVCOM), 模拟南设得兰群岛及长城站邻近海域的潮汐动力过程, 并将模式输出的2015—2017年3年的夏季水位与长城站实测水位对比, 发现模型能够较好地模拟计算海域内的潮汐过程。应用以上的模型结果, 本文还探讨了长城站附近海域往复流和旋转流的分布特征, 发现其最大可能潮差分布呈现东南角大、西北角小, 在乔治王岛东北端和西南端都存在极大潮差的特点。

Abstract: The Antarctic Great Wall Station is located at the southern tip of the Fildes Peninsula on King George Island, Antarctica. Observation of tides in the water adjacent to the Great Wall Station is important for the construction and maintenance of the station and for its operation. In this study, the three-dimensional hydrodynamic ocean numerical model Finite Volume Coastal Ocean Model (FVCOM) is used to simulate the tidal dynamic process near the South Shetland Islands and the adjacent sea area, in which the Great Wall Station is located. By comparing the simulated summer water levels at the Great Wall Station in 2015—2017 with measured water levels, the model successfully simulates tidal propagation in the area. Based on the model results, the distributions of rectilinear and rotary currents in the waters near the Great Wall Station are discussed. The distribution of the maximum possible tidal range is found to be high in the southeast of the area and low in the northwest, with extremely large tidal ranges at the northeast and southwest ends of King George Island.
