Spectral Properties of Lightning Return Stroke
نویسنده
چکیده
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 such as wavelengths, oscillator strengths and excited energies have been calculated for the transitions related to lightning spectra. Compared the calculated results with experimental spectra, it shows that the geographic situation and absolute altitude of observation site have a remarkable influence on the feature of lightning spectra.

Review and Evaluation of Lightning Return Stroke Models Including Some Aspects of Their Application
Four classes of models of the lightning return stroke are reviewed. These four classes are: 1) the gas dynamic models; 2) the electromagnetic models; 3) the distributed-circuit models; and 4) the “engineering” models. Validation of the reviewed models is discussed. For the gas dynamic models, validation is based on observations of the optical power and spectral output from natural lightning. Th...
متن کاملCharacterization 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 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 کاملTall-Structure Lightning Return-Stroke Modelling
A lightning return-stroke model, based on the lightning return-stroke current derivative measured at the Toronto CN Tower is presented in this paper. A 3-section transmission line representation of the CN Tower along with the derivative of the modified Heidler function is used to simulate the measured current derivative signal. Reflections from major structural discontinuities of the CN Tower a...
