Characterization of return-stroke currents in rocket-triggered lightning
[1] We present a statistical analysis of the salient characteristics of current waveforms for 206 return strokes in 46 rocket-triggered lightning flashes. The flashes were triggered during a variety of experiments related to the interaction of lightning with power lines that were conducted from 1999 through 2004 at the International Center for Lightning Research and Testing at Camp Blanding, Fl...
متن کاملOn the transmission line model for lightning return stroke representation
[1] The widely used transmission-line (TL) model of lightning return stroke in a vertical channel is most rigorously represented by a vertical phased array of current sources that produce a spherical transverse electromagnetic (TEM) wave in the case of return-stroke speed v equal to the speed of light c. If the radius of the lightning channel were equal to zero, the equivalent representation co...
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 کاملElectromagnetic 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 کاملSpectral Properties of Lightning Return Stroke
Using a slit-less spectrograph the spectra in the range of 390-660nm for first return strokes of CG lightning flashes have been obtained both in Qinghai plateau, northwestern China and in coastal area of Guangdong, southern China respectively. The heights of two observation sites differ by 2500 meters. Appling the atomic structure theory to the research work on lightning spectra, parameters suc...
