摘要
建立了一个三维硫沉降欧拉模式，模式中比较全面地考虑了硫沉降过程中的物理、化学机制。包括平流、扩散、干湿沉降和积云的垂直输送作用等物理过程，气相化学、液相化学和气溶胶表面的非均相化学等化学过程。其中非均相化学和积云的垂直输送参数化在国内外同类模式中尚不多见。模式结果与实测及其他模式结果的对比表明，该模式能够较好地模拟出ＳＯ２的水平和垂直分布及ＳＯ２－４在降水中的浓度。
A three-dimensional sulfur deposition model is developed In this model detailed physical and chemical processes, such as transport, diffusion, dry and wet deposition, transportation in cumulus cloud, gas phase chemistry, aqueous phase chemistry and heterogeneous aerosol chemistry are considered The main characteristics of our model is the adoption of heterogeneous aerosol chemical process and transportation of pollutants in cumulus cloud The model is evaluated against observations and results of other models Model performs well in explaining distribution of SO 2 in the surface, concentrations of SO 2- 4 in rain water and vertical profiles of SO 2
