南大洋海冰气候特征研究

A Study of the Climate Feature of the Antarctic Sea Ice

应用１９７３～１９８８年海冰资料，将南大洋划分为５个海区，即：２０～８８°Ｅ，９０～１５８°Ｅ，１６０°Ｅ～１３２°Ｗ，１３０～６２°Ｗ，６０°Ｗ～１８°Ｅ，按这５个海区分析了南大洋海冰的空间分布特征及其时间变化特征。这些研究结果，对气候背景的研究是有益的。

This paper uses the sea ice data during 1973- 1988,and divides the South Ocean into fiveregions: 20￣ 88°E, 90￣ 158°E, 160°E￣ 132°W,130￣ 62°W and 60°W￣ 18°E, to analyse the spatial distribution of the Antarctic sea ice extent and its time variation. Some results are very useful to the research of the climatic background.
