【摘要】 利用欧拉型硫沉降模式分析３个个例，讨论了东亚地区不同天气条件下硫总沉降、干沉降和湿沉降。不同天气条件下硫沉降的分布不同。干沉降与污染源的分布有很好的相关性，而总沉降的分布除决定于排放量外，还明显受到降水场分布的影响。２４ｈ硫沉降量一般为１．０～１０．０ｍｇ／ｍ２，最大可达３２ｍｇ／ｍ２，干沉降量的值为１．０～５．０ｍｇ／ｍ２，最大值为１４．８ｍｇ／ｍ２，湿沉降量的值为０．５～７．０ｍｇ／ｍ２，强降水区附近可达２２ｍｇ／ｍ２。更多还原

【Abstract】 The distributions of total sulfur deposition,dry deposition and wet deposition in East Asia are discussed using a Eulerian sulfur deposition model.The distributions are different under different meterorological conditions.Distrbutions of dry deposition are similar to those of emissions.Total depositions are controlled by emissions and influenced by precipitation as well.Daily total sulfur depositions are 1.0～10.0mg/m2 with the peak value of 32mg/m2.Dry depositions are 1.0～5.0mg/m2 and wet depositions vary from 0.5 to 7.0mg/m2 with the biggest value of 22mg/m2 in the areas of heavy rain.更多还原
