摘要
利用中国南极长城气象站和中山气象台常规气象观测及与气象有关的科学考察资料 ,对中国南极气象台站的气候和大气环境特征及其对全球变化的响应进行了研究。研究结果表明 ,南极和邻近地区气候变化存在着时间、空间上的多样性。中国南极长城站和中山站正好处于南极半岛和东南极两个不同的气候区。近 10余年来 ,当位于南极半岛地区的长城站显著增温时 ,位于东南极的中山站恰有较明显的降温趋势。南极地区的温度变化趋势与全球平均变化有较大差异。这种变化和差异很难简单地用全球温室效应来解释。近 7年来 ,中山站地区的大气臭氧总量有减少趋势 ,与全球大气臭氧总量变化趋势相同。在南极地区 ,进一步加强国际合作 ,继续监测包括近地面温度在内的大气要素的变化 ,积极获取代用资料 ,仍是全球变化研究的重要内容之一。
The climate and atmosphere environmental characteristics observed by Chinese Antarctic Meteorological stations, the Greatwall Station and Zhongshan Station, and their relationship with global change are studied by using the meteorological data obtained from Chinese Antarctic Expeditions. Results show that there are varieties of temporal and spatial characteristics of the climate variation trend in Antarctic and adjacent areas. The Greatwall Station and Zhongshan Station locate at different climate regions. During recent more than 10 years, there has been a warmer trend in the area where the Greatwall Station locates while a reverse trend in the eastern Antarctica where Zhongshan Station locates. The temperature anomaly in Antarctic is much different from the average global change, and this kind of change and difference can not be easily explained by global greenhouse effect. The total ozone amount at the area of Zhongshan Station has been decreasing during recent 7 years, which is similar to the trend of the global ozone variation. It is still one of important topics of research on global change to further conduct international scientific cooperation in Antarctica and further make observations of atmospheric change including surface air temperature to obtain the substitution data.
