摘要
利用海冰面积指数 ,分析了南、北极海冰年际时间尺度的时空演变特征。结果表明 :南极海冰具有明显的年际振荡。南极夏季海冰年际异常具有一定的整体性 ,秋、冬、春季海冰年际异常则表现出较强的区域性。北极海冰也具有显著的年际振荡。北极冬、春季海冰年际异常主要发生在格陵兰海、巴伦支海和喀拉海 ,夏。
Analyzed are the characteristics of the v a riations of the Arctic and Antarctic sea ice on interannual basis.The results sh ow that the interannual oscillation of south polar sea ice is obvious,with the a nomalous variation being of entirety (regionality) in summer (autumn,winter and spring). The interannual oscillation of north polar sea ice is also remarkable,w ith the anomalous variation happening mainly over the Greenland Sea,Barents Sea and Kara Sea(east Siberian Sea and Bofft Sea) in winter and spring (summer and a utumn).
