摘　　要：本文主要根据 1 998～ 1 999年南极中山站气压、气温、相对湿度和风的观测资料 ,对其周边地区气象要素变化特征进行了分析 .结果表明 ,中山站地区近期降温倾向明显 ,气温年较差大 ;空气干燥 ,相对湿度小 ;夏半年受下降风影响大 ;常年盛行东风 ,风力较强 .In this paper, the varying feature of meteorological elements in the Zhongshan Station is analyzed according to the measured records of air pressure, air temperature, relative humidity and wind speed from 1998 to 1999. It is shown that in the district of Zhongshan Station, the trend of temperature downfall is apparent in recent year, the air temperature has large annual range, the air is so dry that the relative humidity is small, the east wind prevails and its speed affected by down wind is larger. The feature of continental climate is apparent.
