By using adiabatic air parcel method of multi-component aerosols, this paper analyzes hygroscopic growth characteristics of aerosols in Huangshan area in 2008. Some calculations show that The hygroscopic growth factor f defined as d _{p, wet}/d _{p, dry}, where d _p,wet is the particle mobility diameter under a humidified condition, is closely bound up with particle radius, relative humidity (RH), particle chemical components, vertical velocity and lifting height. The hygroscopic growth of small particles is more significant than that of the large ones. Relative humidity is positively related with the hygroscopic growth factor f. The more relative humidity approaches the critical relative humidity of particles, the more the hygroscopic growth factor f changes with relative humidity. Through increasing the solute soluble inorganic aerosol influences critical saturated ratio so as to make the hygroscopic growth factor f increase. If the role of unsolvable nucleation doesn't be taken into account, the hygroscopic growth of particles will be overestimated. With the velocity rising, the hygroscopic growth factor reduces, and the reduction degree depends on initial relative humidity. The lifting height can influence the hygroscopic growth factor through the change of relative humidity.
