| 摘 要： | 利用IAP/LASG GOALS 4.0海气耦合模式,"显式"考虑了硫酸盐气溶胶的直接作用,并且引入德国马普气象研究所的三维浓度分布资料,模拟计算了硫酸盐气溶胶的辐射强迫.主要结果为:全球气溶胶年平均的辐射强迫为-0.29 W m-2,在IPCC TAR给定的范围内,空间分布上具有明显的地域性,几个大值地区分别为东亚、西欧和北美,它们的中心值均超过-1.5 W m-2,南美、澳大利亚以及非洲南部的辐射强迫介于-0.2～-0.4 W m-2之间,而海洋和偏远的大陆地区,则基本上不受人为硫酸盐气溶胶的影响;计算的东亚地区硫酸盐气溶胶的平均辐射强迫为-0.75 W m-2,约为全球平均的2.5倍,为北半球平均的1.6倍.文中还讨论了全球硫酸盐气溶胶对温室气体辐射强迫的减缓作用.

| Abstract: | The direct effect of sulfate aerosol was explicitly represented in IAP/LASG GOAL S 4 0 coupled model. The model simulates the radiative forcing from 1900 to 199 0 by introducing into the 3-D concentration of sulfate aerosol simulated by MPI in Germany, the results show that the global mean radiative forcing due to sulf ate aerosol is -0 29 W m -2 which belongs to the estimates of the late st IPCC scientific report. The forcing distribution is characterized with suffic iently large in a number of regions including east Asia, western Europe and nort hern America, which all surpass -1 5 W m -2 in their maximum value. Th e radiative forcing in South America, Australia and the south of Africa is gener ally between -0 2 W m -2 to -0 4 W m -2. However, The marine or remote continents were little influenced by anthropogenic sulfate aerosols. |
