摘    要:本文首先采用一线辐射对流模式,分析了乡村型、城市型气溶胶和平流层气溶胶含量增加对全球地表气温的直接影响以及硫酸盐粒子含量增加对全球地表气温的间接影响。然后利用考虑了海洋热惯性作用的EBM/BD模式,模拟了近百年来由于大气中硫酸盐粒子含量变化、火山爆发和大气温室气体浓度增加共同引起的全球地表平均气温变化。结果表明:气溶胶的气候效应在地气系统辐射收支和全球气温变化研究中起着非常重要的作用。

关 键 词:气溶胶  硫酸盐粒子  气候效应

Abstract:Aerosols can affect the global radiation. budget and climate directly thtoughtheir scattering and absorption of solar and thermal radiation and indirectly throughtheir modification of cloud microphysical properties. In this paper, a radiative-convective model is used to analyze the sensitivity of the global surface mean temperature to an increase in the atmoapheric burden of aerosols. The global surface temperature variation in the past century is simulated by using a coupled EBM/BD*model with considering the radiative forcings caused by volcanic aerosols, non-seasalt sulphate aerosols and greenhouse gases. The' comparison between the, simulatedand observed global surface temperature variation shows that the aerosols play avery important role in the global climate variation over the past century.
Keywords:aerosols  sulphate particles  climate effct
