Abstract: We give a general overview and analysis of conditions for the occurrence of transient luminous events in the atmosphere, namely, termed sprites, elves, jets, and lightnings up. The main features of their appearance and manifestations were obtained. Quasielectrostatic fields of the system of thundercloud charges with the use of the Wilson model were simulated. It is found that in the lower atmosphere the decreasing length for the electrostatic field created by a thundercloud is about 10 km. This result is in good agreement with direct measurements. The spatial and temporal dynamics of an electric field in the Earth-ionosphere system was simulated. The obtained results were compared with the analytic solution. Our electric field consideration can be used for further simulation of sprites and jets.
