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.

Key words: Great Wall Station, Zhongshan Station, climate change, AAO
