In this article,a complete thunderstorm electrification model is proposed by adding the aerosol module to the existing two-dimensional thunderstorm electrification model.The SEET case is used to discuss the effect of different aerosol concentration on the electric charge of various particles in thunderstorm cloud.The result shows that a good positive correlation exists between the aerosol concentration and maximum charge density/quantity carried by particles like the cloud droplet,graupel grain,hail or raindrop in the thunderstorm cloud,and the increase of the aerosol particle concentration will bring forward the time of the charges brought by the raindrop to reach its peak.
