| 摘 要： | 运用发展的区域系统集成模式RIEMS,结合Slingo参数化方案,研究了中国夏季硫酸盐气溶胶对云特性(云滴有效半径)的影响及其所产生的间接辐射效应。模拟的云滴尺度分布基本合理,数值在0～10μm之间,但与卫星数据MODIS相比偏小。硫酸盐气溶胶间接辐射强迫7月平均值为-2.58W/m2,空间变化在-10～-1W/m2之间,最大值出现在东北长白山地区,陆地上的负强迫大于海洋。间接辐射强迫与气溶胶浓度分布和云水分布有密切的关系。

Model Study of Indirect Radiative Forcing by Sulfate Aerosol Over China in Summer |

| Abstract: | Regional integrated environment modeling system (RIEMS) was developed and applied to study the effect of anthropogenic sulfate on cloud properties,such as cloud droplet effective radius,and the resulting indirect radiation forcing over China in summer.The simulated cloud droplet size was reasonably within the range of 0～10 μm,and the cloud droplet size was generally smaller than that retrieved from MODIS data.In July,the simulated domain-averaged indirect forcing by sulfate was about-2.58 W/m2 with a range of-10～-1 W/m2 in the study domain.The maximum forcing occurred in the area of the Changbaishan Mountain in northeast China and the forcing was larger over land than that over sea.The indirect radiative forcing was closely related to the distribution of aerosol and cloud water concentrations. |
