| 摘 要： | 采用南、北极海冰面积指数 1°× 1°经纬度格点资料及海平面气压资料 ,运用多种统计方法 ,研究了南、北极海冰的长期变化趋势、突变特征及其与大气环流的联系 ,发现近年来南极冬、春、秋季海冰逐渐减少 ,夏季海冰逐渐增加 ;北极春、夏、秋季海冰均不同程度地减少 ,冬季海冰变化趋势不明显 ;南、北极各季海冰的年际变化均存在一定的突发性 ,大气环流在海冰突变年前后有显著的差异

| Abstract: | With Arctic and Antarctic 1°× 1°(longitude × latitude)sea ice area index data andSLP data,it is investigated,by statistical methods ,that the variation of sea ice both in Arcticand Antarctic and its relation to atmospheric circulation. It is found that, in the past years,sea ice in Antarctic declines in winter, spring and autumn,while it increases in summer. Seaice in Arctic decreases in a certain degree in spring,summer and autumn,but its linear trendis not obvious in winter. Sea ices in Arctic and Antarctic have some abrupt changes in spring,summer,autumn and winter. The atmospheric circulation has remarkable differences before and after the abrupt changes of sea ices. |
