本研究基于IPCC AR5(Intergovernmental Panel on Climate Change:Fifth Assessment Report)中BCC_CSM1.1(Beijing Climate Center Climate System Model version 1.1)和BCC_CSM1.1(m)(Beijing Climate Center Climate System Model version 1.1 with a Moderate Resolution)气候模式的历史试验结果和CRU(Climatic Research Unit)资料, 采用趋势分析和滑动平均等方法检验了两个版本BCC_CSM模式对中亚地区1948～2011年平均地表气温、各热通量及其趋势的模拟性能, 并讨论了不同模式水平分辨率的影响, 结果显示:BCC_CSM1.1和BCC_CSM1.1(m)两个模式均能够模拟出中亚地区显著增温以及感热通量、长/短波净辐射等要素由南向北递减的总体趋势。其中, BCC_CSM1.1(m) 在对中亚地面年平均气温、感热通量和长/短波净辐射空间分布的模拟结果好于BCC_CSM1.1, 但对于气温标准差的模拟, BCC-CSM1.1模式略好于BCC-CSM1.1(m)。模式分辨率的提高, 能够更好地表现出地形的影响, 对气温和各热通量模拟性能改善较大, 在中亚地区年平均气温的模拟中表现出了一定的优势
