Lightning 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 کاملInsights into the ground attachment process of natural lightning gained from an unusual triggered-lightning stroke
[1] We present measured electric and magnetic field and current derivatives from an unusual triggered-lightning stroke that was initiated by a dart-stepped leader and that involved an upward connecting leader. The initial rising portion of the current (integrated dI/dt) waveform is composed of a ‘‘slow front’’ rising to 20 kA in 2.2 ms, followed by a ‘‘fast transition’’ from 20 to 27 kA in 0.2 ...
متن کاملStruck-by-lightning deaths in the United States.
The objective of the research reported here was to examine the epidemiologic characteristics of struck-by-lightning deaths. Using data from both the National Centers for Health Statistics (NCHS) multiple-cause-of-death tapes and the Census of Fatal Occupational Injuries (CFOI), which is maintained by the Bureau of Labor Statistics, the authors calculated numbers and annualized rates of lightnin...
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...
متن کاملCN Tower Lightning Return-Stroke Current Simulation
Different functions have been used to model the lightning return-stroke current with the aid of direct current measurements at tall structures. In this paper, a comparison between the Pulse function and Heilder function is carried out to find out the suitability of each of these functions for simulating the lightning return-stroke current, measured at the CN Tower. An automated system for deter...
