| Abstract: | According to the observation and study of the literature on the ball lightning, the observational characteristics of ball lightning are summarized. Then the theoretical and experimental research status on the ball lightning are introduced, and the model of ball lightning structure is briefly epitomized. Based on linear lightning of the cloud versus earth, a kind of plasma model formed ball lightning is introduced. According to the model, the plasma channel of line lightning collapses into a small region in specific environmental condition, so as to form a ball lightning. The research direction of ball lightning in the future is summed up in the final part of this paper. |
