There is an extensive evidence on the spectacular dust storm generated in Western China during June 1998, (e. g. http://capita.wustl.edu/ASIA-FAREAST; http://www.nrlmry.navy.mil/aerosol). The storm was followed by large transport of mineral aerosol over the Pacific Ocean. In about 10 days after the storm occured, the increased dust concentration was observed on the Western coast of the States.

DREAM (Dust REgional Atmospheric Model) has been used  to simulate this event (http://icod.org.mt/Modelling/hyddyn3.htm). In DREAM, dust concentration continuity equation is driven by the  NCEP/Eta atmospheric model as an on-line component. The dust model has been applied for operational and research purposes at a number of institutions: University of Malta (http://icod.org.mt); University of Athens (http://forecast.uoa.gr); MEDUSE project (http://halo.hi.is/meduse/index.html); Middle East Technical University, Turkey; Meteorological Service, Cyprus; Hebrew University of Jerusalem). DREAM,  initially designed in the framework of the LAND-3 Project of the World Laboratory, has been recently further developed and improved by joint efforts of the University of Athens and the University of Malta. The model can be easily modified to simulate/predict other atmospheric aerosols, as well (e. g. recent tests with mercury life cycle at the Athens University). 

Preliminary results of the simulated evolution of dust load during the Chinese dust event 1998 are shown below. The results are compared with TOMS satellite images (http://jwocky.gsfc.nasa.gov/aerosols/china_dust.gif). The model fields show a good agreement with the observations.
