中文摘要: 利用1973-1986年海冰面积指数资料对其月际变化特征进行了分析,结果发 现:①50oS以南海域海冰面积月际变化特征与60-69. 75oS的非常相似;②在某些地 区,海冰月际变化有纬向传播趋势;③一般而言,9月份海冰最多,2月份海冰最少;但 在某些地区,出现最多或最少的月份比上述月份可相差1个月。
Abstract:The inter-monthly sea ice variation in the Southern oceans has been studied by the use of the area index data of sea ice from 1973 to 1986. The results show that: (1) the inter-monthly variation pattern of sea ice area in the latitude belt of 50°-79. 75°S is similar to that of 60°-69. 75°S; (2) in certain longitudes,this variation shows a tendency of Eastward (or west ward) propagation; (3) in general, the maximum and minimum of sea ice area appear in February and September respectively. But in certain longitudes, the months occurred extreme values can move up or delay.
