The east limb of the Ross Gyre approaches the western Amundsen Sea, thereby exerting an influence on the surface circulation dynamics. This study investigates the impact of the zonal movement of the eastern boundary of the Ross Gyre on the surrounding surface geostrophic circulation in January. Specifically, a zonal shift of the eastern boundary of the Ross Gyre induces a substantial shelf-basin circulation within the Amundsen Sea. The findings of this study provide valuable insights into the influence of the Ross Gyre on the exchange processes between the Amundsen Sea shelf and basin.

罗斯环流对南极洲阿蒙森海表面环流的影响

罗斯环流东翼接近阿蒙森海西部，从而对地表环流动态产生影响。本研究调查一月份罗斯环流东部边界的纬向运动对周围地表地转环流的影响。具体而言，罗斯环流东部边界的地带性变化导致阿蒙森海内出现大量的陆架盆地环流。这项研究的结果为了解罗斯环流对阿蒙森海陆架和盆地之间交换过程的影响提供了宝贵的见解。
