中文摘要: 根据2002年在ACE Asia和TRACE P试验中获得的亚洲区域污染源排放资料，结合由MICAPS
能见度观测资料估算而得的颗粒物排放资料，利用美国EPA最新发展的Models 3/CMAQ模
式系统，模拟研究了2002年3月华北地区发生的一次强沙尘暴个例。结果表明，（1）模拟的
各气态污染物的时空演变及相互关系与已有的观测结果基本一致。（2）颗粒污染物的模拟
结果也反映了已有的观测事实，粗细颗粒物呈一致的先降后升日变化趋势；沙尘过程前期，
颗粒物污染主要来源于近地面污染源；沙尘期间，颗粒物污染主要源自外界沙尘的高空输送
，且粗颗粒物污染是此次过程的首要颗粒污染。（3）该模式系统可用于沙尘气溶胶研究的
进一步开发与利用。
Abstract:A strong sandstorm of North China in 2002 was simulated with the Models 3/CMAQ
system newly developed by US EPA. The pollution source data were based on the AC
E Asia and TRACE P Experiments in 2002, and the particulate emission data were
estimated by the visibility range from MICAPS observations. The results show th
at, (1) the spatio temporal evolvement and the mutual relationship of gas
eous pollutants are consistent with the common regulation derived from observati
ons. (2) The simulation of coarse PM also reflects the observational facts: The
diurnal trend of both fine and coarse PM first falls and then raises; The PM so
urce before
SDS is near surface emission while the PM source after SDS becomes upper air’s
transportation of dust; Pollution of coarse PM is dominant; （3） This air qual
ity model system can be used for further development on dust aerosols.
