1Arctic Sea Ice and Eurasian Climate:A Review显示文摘The Arctic plays a fundamental role in the climate system and has shown significant climate change in recent decades,including the Arctic warming and decline of Arctic sea-ice extent and thickness. In contrast to the Arctic warming and reduction of Arctic sea ice, Europe, East Asia and North America have experienced anomalously cold conditions, with record snowfall during recent years. In this paper, we review current understanding of the sea-ice impacts on the Eurasian climate.Paleo, observational and modelling studies are covered to summarize several major themes, including: the variability of Arctic sea ice and its controls; the likely causes and apparent impacts of the Arctic sea-ice decline during the satellite era,as well as past and projected future impacts and trends; the links and feedback mechanisms between the Arctic sea ice and the Arctic Oscillation/North Atlantic Oscillation, the recent Eurasian cooling, winter atmospheric circulation, summer precipitation in East Asia, spring snowfall over Eurasia, East Asian winter monsoon, and midlatitude extreme weather; and the remote climate response(e.g., atmospheric circulation, air temperature) to changes in Arctic sea ice. We conclude with a brief summary and suggestions for future research.GAO Yongqi SUN Jianqi LI Fei HE Shengping Stein SANDVEN YAN Qing ZHANG Zhongshi Katja LOHMANN Noel KEENLYSIDE Tore FUREVIK SUO Lingling 2015Advances in Atmospheric Sciences2015,32,1:21
2近40年北极海冰范围变化特征分析显示文摘随着全球变暖,北极海冰正在发生快速变化。文中使用北极地区1972年1月—2012年12月海冰密集度卫星遥感资料,计算了北极海冰范围,讨论了北极海冰范围的各月年变化趋势,并分析了北极海冰范围与北半球温度异常、大气中CO2浓度的关系。分析结果表明:近40年北极海冰呈显著减少趋势,9月份减少最快;北极海冰的减少滞后于北半球2—4月的异常高温;北极年海冰范围与大气中CO2浓度为负相关,相关系数r为-0.94,说明大气中CO2浓度的增长影响了包括气温在内的气候变化要素,而导致北极海冰消退。薛彦广 关皓 董兆俊 陈飞 2014海洋预报2014,31,4:14
