    Whistler intensities above thunderstorms

  • Original language description

    We report a study of penetration of the VLF electromagnetic waves induced by lightning to the ionosphere. We compare the fractional hop whistlers recorded onboard the DEMETER satellite with lightning detected by the EUCLID network. We have developed software for automatic detection of the fractional hop whistlers in the VLF spectrograms. We obtain a map of mean amplitudes of whistler electric field as a function of latitudinal and longitudinal difference between the location of the causative lightning and satellite magnetic footprint. The mean whistler amplitude monotonically decreases with horizontal distance up to 1000 km from the lightning. The maximum of whistler intensities is shifted from the satellite magnetic footprint 1° owing to the oblique propagation. The average amplitude of whistlers increases with the lightning current. At nighttime, the average amplitude of whistlers is about three times higher than during the daytime.
