摘要
本文利用长城站 1 985~ 1 996年气压和风的观测资料以及所接收的气象传真图对长城站的气压场和风场分冬夏两半年进行了天气学分析 ,结果表明 :长城站地区气压的年际变化可能存在 4~ 5年周期 ;冬半年盛行 ESE风 ,夏半年盛行 WNW风 ;夏半年盛行东高西低 (威德尔海为高压区 ,南极半岛及别林斯高晋海为低压区 )的气压场形势 ,冬半年盛行西南高东北低 (南极半岛以西为高压区 ,威德尔海一带为低压区 )的气压场形势。
WT5BZ] Based on the ten year(1985-1996) observational data and the facsimile charts from Chinese Antarctic Great Wall Station. The pressure and wind fields were separated into summer season(January-June) and winter season(July-December),and then analyzed synoptically. The characteristics of these fields monthly and annual variations were pointed with the corresponding synoptic situations. This result will be helpful in the future synoptic meteorology and climatology research.
