利用2012年全年的ASCAT散射计风场数据，对55°S以南的南极周边海域海面风场开展了时空分布特性统计分析。结果表明：对于南极周边海域，7月平均风速最大，为12 m·s－1，12月平均风速最小，为8 m·s－1，冬季大于夏季；该区域平均风速主要在9—12 m·s－1之间，全年出现的天数＞280天，约占全年的77％；风速＞10 m·s－1所占比例也是冬季大于夏季。从全年来看，南极周边海域在冬季（4—6月）和春季（7—9月）风速普遍较大。该区域0°W—60°W海域内风速明显比其他海域要小。

We performed statistical analysis of spatial and temporal distribution characteristics of the sea surface wind field in the Southern Ocean between 55°S and 90°S,using ASCAT scatterometer wind field data for 1 January 201 2 to 31 December 2012.The maximum monthly mean wind speed of 12 m·s-1 occurred in July.The minimum monthly mean wind speed of 8 m·s-1 occurred in December.The monthly mean wind speed was higher in winter than in summer.The regional average wind speed was between 9 and 1 2 m·s-1 ,and occurred on more than 280 days in 201 2.The number of days with wind speed >1 0 m·s-1 was higher in winter than in summer.During 201 2,the wind speed in winter (April to June)and spring (July to September)was higher than in summer (Octo-ber to December)and autumn (January to March).The wind speed in the area between 0°W and 60°W was lower than in other parts of the Southern Ocean.
