南极威德尔海冰间湖形成机制的研究进展

针对南极威德尔海冰间湖的特点及影响，本文介绍了有关威德尔海冰间湖形成研究的进展情况，并对存在的问题以及未来的发展进行了分析和阐述。结果说明：动力因素、热力因素和热动力因素都只是威德尔海冰间湖形成和维持的某一方面的控制和影响因子。对威德尔海冰间湖更深入的研究，应该充分考虑较大尺度的海洋-海冰-大气相互作用。

Advances in Studies on Mechanism of the Weddell Polynya Formation

Occurrence of Weddell Polynya influences Antarctic Bottom Water formation and may be one of the major sources of climate variability on the decadal to centennial time scales. In this circumstance, the Weddell Polynya became a new focus of the Southern Ocean research in the last decade. The recent advances in the studies on the Weddell Polynya, including the mechanism for its formation and its affection on atmosphere and ocean, were reviewed in this paper. The unsolved problems in the previous research work and possible advances in the future studies were also commented. The dynamic, thermal and thermodynamic aspects about the occurrence and maintenance of Weddell Polynya are likely ingredients. For fully understanding the initiation and maintenance of Weddell Polynya,the atmosphere-sea ice-ocean interaction in large scale should be considered.
