摘要: 利用世界气候研究计划的第五阶段模式比较计划(Coupled Model Intercomparison Project Phase 5,CMIP5)提供的参加政府间气候变化专门委员会第五次评估报告(The Fifth Assessment Report of Intergovernmental Panel on Climate Change,IPCC AR5)的23个全球气候模式和第三阶段模式比较计划/第四次评估报告CMIP3/AR4的19个全球气候模式,考虑高排放典型浓度路径RCP 8.5(Representative Concentration Pathway 8.5)和排放情景特别策划SRES A2(Special Report on Emission Scenarios A2)、中等排放(RCP 4.5和SRES A1B)和低排放(RCP 2.6和SRES B1)各3种温室气体排放情景,预估21世纪中国近地层(距地面10 m)风速变化。结果表明:21世纪中国区域近地层年平均风速呈减小的趋势,随着温室气体排放浓度的增加,年平均风速减小趋势的程度依次显著,模式预估风速减小趋势的一致性也依次增加。CMIP5和CMIP3模式的预估结果均表明21世纪中国西部地区(N和SW区)年平均风速呈减小的趋势,东部地区(NE和SE区)年平均风速呈增加的变化趋势。与21世纪前期(2006-2015年)相比,21世纪后期(2090-2099年)中国西部、华北北部至东北南部地区风速偏小,东北北部、华北南部至华南大部地区风速偏大。温室气体排放浓度越大,21世纪后期中国冬季(夏季)风速偏小(偏大)于21世纪前期的范围越大,偏小(偏大)程度越明显。

Abstract: The change of surface wind speed was projected by 23 Climate models from the CMIP5 (Coupled Model Intercomparison Project Phase 5) for IPCC AR5 (Intergovernmental Panel on Climate Change Fifth Assessment Report) adapted by WCRP (Word Climate Research Programme) and 19 Climate models from the CMIP3 (Coupled Model Intercomparison Phase 3) for IPCC AR4 (Intergovernmental Panel on Climate Change Fourth Assessment Report) adapted by WCRP (Word Climate Research Programme).The human emission scenarios used the RCPs (Representative Concentration Pathways) including RCP2.6,RCP4.5 RCP8.5 from CMIP5 and the SRES (Special Report on Emissions Scenarios) including B1,A1B,A2 from CMIP3.The results show that the mean annual wind speeds would decrease slightly in China in the 21st century.The mean wind speeds would reduce more significantly with the increase of human emission concentration.Both CMIP5 and CMIP3 project that the mean annual wind speed in Western China (Northern and Southwestern parts) would decrease in the 21st Century and would increase in the eastern region.Compared with that in the early period of the 21st Century (2006-2015),wind speed would decrease in the south of Northeast China,north of North China and West China,while it would increase in the south of North China,South China and the north of Northeast China in the late 21st Century (2090-2099).With the increase of human emission concentration,the negative (positive) deviation ranges in wind would enlarge and the corresponding center value would be more concentrated in winter (summer).
