北极海冰对全球气候变化起重要的指示作用。除了海水冻结和融化过程以外,通过弗拉姆海峡的海冰输出也是影响北极海冰质量变化的重要动力机制。观测数据,尤其是多源卫星遥感数据(尤其是辐射计观测数据)在获取大尺度连续观测方面具有独特的优势,在研究北极海冰输出面积通量变化方面有着广泛应用。本文总结了北极弗拉姆海峡、其它通道(S-FJL、FJL-SZ、加拿大群岛、Nares海峡通道)海冰输出面积或体积通量,着重介绍了弗拉姆海峡不同年龄海冰输出情况,并总结和分析了影响北极海冰输运的大尺度大气活动模态。最后,本文阐明现有研究的不足之处以及未来北极海冰输出方面研究的突破方向。 |

Abstract: |
Arctic sea ice is an important indicator of global climate change. In addition to the freezing and melting process of sea water, the sea ice output through the Flamm Strait is also an important dynamic mechanism affecting the mass change of Arctic sea ice. Observation data, especially multi-source satellite remote sensing data (especially radiometer data) have unique advantages in obtaining large-scale continuous observation, and are widely used in studying the variation of Arctic sea ice output area flux. In this paper, the sea ice output area or volume flux of other channels (S-FJL, FJL-SZ, Canada Islands Nares Channel) is summarized, with emphasis on the sea ice output at different ages in the Flamm Strait. The large scale atmospheric active modes affecting the transport of Arctic sea ice are summarized and analyzed. Finally, this paper clarifies the deficiency of the present research and the breakthrough direction of the future Arctic sea ice output. |
