In this paper we have reviewed the main achievements of research on thunderstorm charged models in the last century.We have derived the Wilson's dipole model and Amoruso Lateral's charged disk model in detail and achieved their analytic solutions.We have analyzed every model's advantage and disadvantage.According to the AmorusoLattarulo's charged disk model,a thunderstorm element linear weighting charging model is established to adapt the research of the new-style lightning protection system.The weight matrix could be fitted by inversion.We have derived inversion expression.This new model could simulate multilayer charge structure that had been observed in thunderstorms and is proved to be logical.For a representational calculation example we gave the result that the max background field is 19 kV·m~(-1) which dovetailed with the proverbial observed result of the earth's surface field.
