【摘要】：针对1979~2014年南北极海冰重要物理参量变化及其与全球气候之间关系的研究空缺问题,进行了南北极海冰长时间序列变化特征研究。该文利用1979~2014年被动微波辐射计海冰密集度产品基于线性倾向估计方法分析36年来南北极海冰密集度变化;由海冰密集度产品得到南、北极海冰范围,分析年际及月际变化,结果显示北极海冰范围明显减小,南极海冰范围略微增大;结合南方涛动指数(Southern Oscillation Index,SOI)和全球平均海平面高度(Global Mean Sea Level,GMSL),指出海冰范围的突变时间,并得出GMSL变化与海冰范围的关联,南极海冰范围变化与SOI之间存在着明显的相关性,GMSL逐年上升,与海冰范围变化呈现显著的负相关。
[Abstract]:In this paper, the characteristics of the long time series variation of Arctic sea ice are studied in view of the gaps in the study of the variation of the important physical parameters and the relationship between the physical parameters and the global climate during the period from 1979 to 2014.Using the passive microwave radiometer sea ice intensity product from 1979 to 2014, based on the linear tendency estimation method, this paper analyzes the variation of the sea ice concentration in the Arctic and the south in the past 36 years, and analyzes the interannual and inter-monthly variations from the sea ice concentration products to the range of the sea ice in the south and the north.The results show that the range of Arctic sea ice decreases obviously, and the range of Antarctic sea ice increases slightly, combining the Southern Oscillation Index (SOI) and the global mean sea level height (GMSL), the abrupt change time of sea ice range is pointed out.The correlation between GMSL and sea ice range is obtained. There is a significant correlation between GMSL and SOI, and a significant negative correlation is found between SOI and sea ice range.
