The electrical characteristics of thunderstorms in four regions with different altitudes, including Naqu of central Tibetan Plateau, Datong of Qinghai, Zhongchuan and Pingliang of Gansu, have been analyzed. The results show that the electrical characteristics of thunderstorms in four regions have the difference and commonness. According to the polarity of electric field underneath thunderstorm, the thunderstorm in Chinese inland plateau can be divided into two types, normal-type and special-type, with the former being similar to that in the lower altitude regions in summer and the later characterized by a larger-than-usual lower positive charge center (LPCC) at the base of thunderstorm. The ratio of special-type thunderstorm increases with the altitude of the region. By combining the meteorology parameters, the electrical characteristics of thunderstorm in four regions are discussed in detail. It is find that some of parameters have obvious difference in study regions, especially, the temperature difference of surface and air at 2 m highs (T_0-2m) and warm cloud depth (WCD) have obvious indication on the intensity of LPCC. Usually, a larger value of  T _0-2m and smaller value of WCD indicate a stronger LPCC of thunderstorm, while a smaller value of  T _0-2m and larger value of WCD induced thunderstorm with a weaker LPCC.The results of model show that the intensity of charge region for two types of thunderstorm has obvious difference because of the density of precipitation particles. The intensity of LPCC is likely to be directly influenced by updraft and WCD of thunderstorm.
