Radiation Field Spectra of Long-duration Cloud Flashes
(English)In: IEEE transactions on electromagnetic compatibility (Print), ISSN 0018-9375Article in journal (Refereed) Submitted
The radiation electric fields produced by long-duration cloud flashes have been Fourier analyzed to determined the frequency spectrum in the range of 10 kHz to 10 MHz. The flashes were recorded within a distance of less than 20 km. The spectrum was normalized to 50 km distance and it shows a f-1 dependence within the entire frequency range.
