【摘要】 在过去的100年中,北极温度升高的速率几乎是全球平均速率的两倍,尽管人为长生命期的温室气体(GHGs)在气候系统辐射强迫中占主导地位,黑碳气溶胶和其它短生命期的污染物却能很好地解释北极气候增暖较快的原因。因此,减少人为黑碳气溶胶排放将成为缓解北极迅速变化的重要策略。介绍北极黑碳气溶胶研究现状,讨论它在北极变暖中扮演的角色,分析当前北极黑碳气溶胶研究中存在的问题,展望深入开展黑碳气溶胶观测研究的必要性和紧迫性。更多还原

【Abstract】 Over the past 100 years, the average temperature increasing rate in the Arctic is about twice as the global average temperature increasing rate. Althouth the anthropogenic long-lived greenhouse gases play a predominate role in radiation forces in weather system, the black carbon aerosol and other short-lived pollutants could also explain a significant fraction of the Arctic warming. Therefore, reducing the emission of black carbon aerosol into the atmosphere will cool the planet and make a negative feedback to Arctic warming. The research progress of black carbon aerosol in the Arctic and their impacts on the Arctic climate are reviewed.更多还原
