摘要：

本文使用了WDC-A提供的按WMO标准格式化的SGRID海冰资料(1973～1989)和NSIDC提供的SMMR和SMM/1的亮温微波资料(1978～1994),将这些资料同化处理使海温序列延长为1973～1994年。利用上述资料研究海冰的长期变化趋势,发现70年代前期海冰迅速增多到中期达最大值,后期到80年代前期迅速减少到最少,80年代海冰持续偏少或在平均值附近振动,90年代前期海冰又开始缓慢增多。但总值仍比70年代前、中期少的多。另外,海冰的区域性变化差异很大,特别是威德尔海区的海冰其变化转折期都先于其它海区的变化,具有领先和正反馈于其它冰区的海冰。

n this paper, the antarctic sea ice SIGRID data in 1973-1989 standardized by WMO format provided by WDC-A and the SMMR and SMM/1 brightness microwave data in 1978 1994 provided by NSIDC are used. TIses data are simulated-processed to enlong year numberof the sea ice data as in 1973-1994.Using these data to study the long-range variation trend of sea ice, it is fotmd that, theAntarctic sea ice increased from early 1970s’ and attained the maximum value in coddle1970s’. Since later 1970s’, sea ice rapidly decreased to the minimum in early 1980s’. It was suatainedly less or varied about the mean value in whole the 1980s’. In early 1990s’, sea icebegan to increase again slowly, but the total value was still less than in early-middle 1970s’.In addition, the regional difference of sea ice variation is very 18lge. It is specially true forsea ice of the Wedded Sea region with its variation transition time prior to all other sea regions.Sea ice variation of the Wedded Sea Plays a leading role on and give a peitive-negative fedback to other sea ice regions.
