对南极地区温度和海冰的时空变化特征及相互关系进行的初步研究结果表明：近３０余年来南极地区有显著的变暖趋势，时空差异比较明显。其中以南极半岛地区的变暖趋势最大，为整个东南极沿岸增温率的２～３倍。近２０年来，整个平均的南极海冰和温度的变化趋势相反，年际变化的相关关系不显著。经过聚类分析划分出不同的气候区，能清楚地显示出某些区两者的关系。海冰与同区沿岸温度距平相关信号最强区在南大西洋至西南太平洋海域。
The results of preliminary study on the temporal and spatial variation of temperature and sea ice in the Antarctic region show that there is a significant warming trend in the Antarctic over the past 30 years and the spatial and temporal differences are obvious. Among them, the warming trend in the Antarctic Peninsula is the largest, which is 2 ~ 3 times of the warming rate of the whole Southeast Coast. In the recent 20 years, the trend of Antarctic sea ice and temperature in the whole average is opposite, and the inter-annual variation is not significant. Clustering analysis of different climatic zones, can clearly show the relationship between the two areas. The strongest sea ice related to the anomalous temperature along the coast of the same region lies in the area from the South Atlantic to the Southwest Pacific Ocean.
