The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.
