摘要
本文利用长城站 1 985年至 1 996年的观测资料和气象传真图对南极长城站地区的温度场 ,湿度场以及降水情况进行了天气学分析 ,结果表明常年低温、高湿、长时间降水是长城站的天气特点。长城站地区夏半年盛行的东高 (威德尔海为高压区 )西低 (南极半岛及别林斯高晋海为低压区 )和冬半年盛行的西南高 (南极半岛以西为高压区 )东北低 (威德尔海一带为低压区 )的气压场形势 ,南半球西风带独特的低压气旋活动以及副极地海域特殊的冰雪漂流下垫面造成了该地区的天气特点。
Based on the ten year (1985-1996) observational data and the facsimile charts from Chinese Antarctic Great Wall Station. The temperature, humidity fields and precipitation were studied. The result showed that low temperature, high humidity and long precipitation days are the significant characteristics in Great Wall Station area. This weather type was affected mainly by the local pressure fields, the activity of polar cyclones and the sea surface with drifting ice and snow in sub-polar region.
