Lightning electromagnetic radiation field spectra in the interval from 25 to 100 MHz

Lightning electromagnetic radiation field spectra in the interval from 25 to 100 MHz

By means of a fast Fourier transform (FFT), average energy spectra in the interval from 25 to 100 MHz are presented for most of the components that produce large radiation field pulses from lightning: first and subsequent return strokes; stepped and dart leaders; preliminary breakdown and intracloud...

Zusammenfassung:By means of a fast Fourier transform (FFT), average energy spectra in the interval from 25 to 100 MHz are presented for most of the components that produce large radiation field pulses from lightning: first and subsequent return strokes; stepped and dart leaders; preliminary breakdown and intracloud K changes.
