摘要:

利用长城和中山站的多种气象观测资料, 揭示了南极气候在近15—30 年全球气候变化关键时期的最
新动态及其对南极涛动变化的响应。结果显示, 近15 年来, 位于南极半岛地区的长城站增暖趋势减缓且有
变冷迹象, 并伴随气压下降和降水增多的趋势, 表明全球增暖停滞期南极半岛经历了与过去几十年长期趋
势有所不同的新变化, 而位于南极大陆沿海的中山站气象要素变化趋势相对平缓, 表明南极半岛和南极大
陆气候变化特征存在显著的区域性差异。两站多个气象要素与南极涛动指数显著相关, 两站温度与南极涛
动相关关系相反等研究事实说明了两站气候与南极涛动及其对应的大气环流区域特征有着密切的联系。

Abstract:

Climate change in the Antarctic during the recent 15–30 years, the key period of global climate change,
has been detected in observations acquired at the Great Wall (GW) and Zhongshan (ZS) Stations. Data show
the Antarctic Peninsula has experienced a cooling trend during the recent 15 years, in conjunction with a
declining trend in pressure and an increasing trend in precipitation, reflecting some new changes that have
occurred during the global warming hiatus. Meanwhile, the data from the ZS station show relatively flat
trends compared with the GW station, implying obvious regional climatic differences between the Antarctic
Peninsula and the eastern Antarctic continent. Investigation of the correlation between multiple meteorological
parameters and the Antarctic Oscillation (AAO) indicates significant correlation between the AAO
and climate at both stations. The different responses to the AAO at the GW and ZS stations might be attributable
to the regional characteristics of the atmospheric circulation corresponding to the AAO.
