| 摘 要： | 本研究收集整理了东亚地区一个黑碳气溶胶的排放源,并利用一个三维化学输送模式系统模拟研究了东亚地区春季黑碳气溶胶的输送和演变过程.黑碳气溶胶浓度的模拟值与地面观测站和观测船获取的监测值相比,模拟值与监测值具有良好的一致性,这表明本研究收集整理的黑碳气溶胶的排放量及其分布是基本合理的,模式系统较好地反映了黑碳气溶浓度的时空分布和变化趋势,再现了许多观测到的重要特征.模拟结果表明,东亚地区春季间隙性的长距离输送对于西北太平洋海域的黑碳气溶胶浓度分布具有非常重要的影响.

| Abstract: | We use a three-dimensional chemical transport modeling system to investigate the transport and evolution processes of black carbon aerosol in East Asia during springtime based on a newly compiled regional emission inventory of black carbon aerosol for East Asia. Simulated black carbon aerosol mixing ratios are compared with observational data collected at ground stations and aboard a vessel. The comparison shows that simulated values are in good agreement with observed ones, and the model system captures the temporal and spatial variations in black carbon aerosol concentrations reasonably well, and reproduces many observed important features. Analysis of model results indicates that the intermittent long-range transport plays an important role in black carbon aerosol concentration distribution over the northwestern Pacific during springtime in East Asia. |
