The article is devoted to such a natural phenomenon as ball lightning. The relevance of the work is due to the fact that the phenomenon itself is widespread, but in itself has not been sufficiently studied. In it, the ball lightning is considered as a plasma ball. The main purpose of the work is mathematical modeling of the lightning temperature field taking into account radiation heat transfer. Based on the obtained result, an analysis of the behavior of the temperature field was carried out.

Based on various radiation components in the spectra of lightning return stroke processes, the temperature of the lightning channel is diagnosed by different methods. Combining with the synchronized electric field data and optical pictures of the lightning channel, the radii of the core current channel and the luminous channel are estimated. On the basis of the above mentioned facts, according to the heat conduction equation, the channel temperature distribution along the radial direction of the lightning return stroke channel is also achieved. The results from six lightning return strokes show that for the core current channel and luminous channel, the radii are in the range of 0.66–1.01 cm and 5.03–7.96 cm, respectively, and the corresponding channel temperatures are 27 300–30 300 K and 3300–5800 K, respectively. Within an average radius of around 1.76 cm, channel temperatures are above 20 000 K and fall sharply along the radial direction while gradually decline outside this range. The radii of the glowing edge with a temperature of around 500 K are first estimated, around 6.94–13.0 cm.

RF electromagnetic pulses (EMPs) generated from gas discharge can not only cause serious interference or damage to electronic equipment but also be utilized in many new applications. In this paper, we establish an experimental platform for studying radiation characteristics of RF EMP from spark discharge plasma at atmospheric pressure. The influences of discharge voltage, electrode configuration, and storage capacitance on the amplitude-frequency characteristics of RF EMP are analyzed. A combined dipole-loop antenna model is proposed to describe the radiation process of EMP from spark discharge plasma. The results show that the frequency spectrum of RF EMP from spark discharge plasma mainly focuses on three intervals, namely, (0–50) MHz, (50–100) MHz, and (100–200) MHz. The radiated electric field intensity of EMP in all frequency bands enhances with the increase in discharge voltage or storage capacitance. Because of the polarization mismatch, the received field intensity in the ball-plate electrode configuration is the weakest compared to the plate-plate and ball-ball electrode. The whole radiation process of EMP from spark discharge plasma can be simulated by a combined dipole-loop antenna model well. The dipole antenna and loop antenna models are used to depict the radiation process of EMP during the discharge transient process and subsequently the energy releasing process, respectively. These results provide some fundamental knowledge for further study of RF EMP from gas discharge.
