%X Using the 3D dynamics electrification coupled model, we simulate the effect of electric activity on hail growth and shooting on the surface during thunderstorms. The results indicate that the hail with charge and strong electric field make precipitation and diameter of hail particles on the ground increase 50% and 0.7mm , respectively, and the time of hail shooting lag 3 minutes. Effect of microphysical growth process of hail through the strong electric field act on the fall speed of precipitation elements is discussed. Electric action mainly influences collection and melting process of hail. Source and sink of hail decrease, and sink decrease more. So, the total amount of precipitation of hail will increase, and the number of hail particles decreases due to electrical effects. It means that hail particles become bigger and eaier to fall.
