Electromagnetic models of the lightning return stroke
[1] Lightning return-stroke models are needed for specifying the source in studying the production of transient optical emission (elves) in the lower ionosphere, the energetic radiation from lightning, and characterization of the Earth’s electromagnetic environment, as well as studying lightning interaction with various objects and systems. Reviewed here are models based on Maxwell’s equations ...
متن کاملElectromagnetic Field Due to Lightning Strikes to Mountainous Ground
The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...
متن کاملLightning Return Stroke Speed
The available experimental data on return stroke speed for both negative and positive lightning are reviewed. The often assumed relationship between the return-stroke speed and peak current is shown to be generally not supported by experimental data. Reasons for the return-stroke speed being lower than the speed of light are discussed. Index Terms Lightning return stroke, propagation speed, pea...
متن کاملReturn stroke current profiles and electromagnetic fields associated with lightning strikes to tall towers: Comparison of engineering models
In this paper, we compare five engineering return stroke models, extended to include the presence of an elevated strike object, namely the Bruce–Golde (BG) model, the transmission line (TL) model, the traveling current source (TCS) model, and the two modified TL models (MTLL and MTLE). The model-predicted current profile along the channel and along the strike object, as well as radiated electri...
