Numerical Simulation On The Fractal Channel Of Intracloud Lightning Discharge

A numerical simulation method for the fractal channel of intracloud lightning discharge is presented, and the influence of the horizontal scale of the thundercloud on the fractal dimension of the discharge channel is also analyzed. The results show that the simulated intracloud lightning discharge channel has obvious fractal structure. The larger the horizontal scale of the thundercloud, the more obvious the branch of the channel and the greater the fractal dimension of the channel.
