摘要
本文综述了北极海冰面积变化与大气遥相关型研究工作中的一些主要结果。诊断分析表明，北极海冰面积变化具有3－4年的振荡周期，大气中的遥相关型不仅与海冰面积变化的区域有关，还与海冰面积的振荡频率有关．海冰面积变化与大气遥相关型是互相维持的，一方的加强有利于另一方的加强，本文最后还对北极海冰和赤道中、东太平洋海温对北半年冬半年中纬度大气环流影响的相似性等问题进行了讨论。
In this paper, sotne results of the study about the variation of the arctic sea ice cover and tcleconnection patterns are synthesized. The variation of the arctic sea ice cover has a period of 3- 4 years. Atmospheric teleconnection patterns not only are related with region of sea ice cover, but also with frequency of the variation of sea ice cover. The variation of the arctic sea ise cover and atmospheric teleconnection patterns support and intensify each other. In the end of this paper, some analogy of the influence of the Arctic sea ice on the mid - latitude general circulation in Northern Hemisphere winter to one of the SST in the central eastern equatorial Pacific is discussed, etc.
