摘要
利用1989—2008年南极中山站及戴维斯站的气象观测数据统计分析了表面气温、气压、风向风速和相对湿度的年际、年和日尺度变化特征,并讨论了各气象要素的长期变化趋势。分析结果表明中山站年均气温趋于升高,气压趋于下降,但变化趋势并不明显,说明在全球气候变化大背景下,南极中山站的大气要素仍保持相对稳定。但也有一些比较显著的变化趋势,如风速减弱,以及秋季气温增暖趋势等。
Based on the meteorological observation data from 1989 to 2008 at Zhongshan and Davis stations,Antarctica,the features of surface air temperature,air pressure,wind direction,wind speed and relative humidity were studied,and the study focused on the long-term variation trend,both annually and seasonally.The results showed an increasing tendency in annual temperature,a linear decline in annual air pressure.However,none of these tendencies were significant,which proved that the air condition in this region was relatively stable,although in the context of global climate change.Moreover,there was a significant downward trend in annual/summer mean wind speed,and a warming trend in autumn air temperature.
