It is helpful to go deep into understanding the acid rainfall through studying the relation of two centers between aciddeposition and rainfall and the relation of intensity between them.We adopt a three-dimensional Eulerian regional aciddeposition model,or NCAR-RADM,to calculate regional chemical concentrations and dry and wet depositions ofacids.The temporally and spatially varied meteorological field is provided by a mesoscale meteorological model,vertion4.We calculate dry and wet depositions of acids in eight kinds of different rainfall distributions.The results show thatthe wet depositions of acids near pollutant source is very sensitive to rainfall intensity in initial stage.The distribution ofacid wet deposition will tend to that of rainfall intensity when rainfall intensity is small in source.And it will tend to thatof initial pollutant concentration when rainfall intensity is large in source. 相似文献
