By employing the finite-difference time-domain method, the processes of electric field variation and morphological development of the optical radiation field of ELVEs and sprite halos were simulated in this article. Simulations of ELVEs show two optical radiation field centers, with a concentrated luminous zone from 85 to 100 km and an inner weaker...

... µí± 2.688 10 m , and í µí± is taken from the NRLMSISE-00 atmospheric parameter model. As shown in Figure 5, neutral air density is closely related to air breakdown threshold (í µí°¸)µí°¸). Based on the í µí°¸3µí°¸3.2 10 í µí± í µí± ⁄ [33], the smaller the neutral air density is, the lower the breakdown threshold is, and the more easily air is broken down. ...

An unresolved issue in the physics of lightning is an explanation for lightning proceeding to the ground by successive luminous steps separated by “dark” times of many microseconds. There is also no explanation of the structure of the dark column connecting the streamer step with the cloud that can be km in length, is electrically conducting, yet h...
