A Review of the Frequency Spectrum of Cloud-to-Cloud and Cloud-to-Ground Lightning

Recent developments in equipment in the field of atmospheric electricity has made possible a more detailed study of cloud-to-cloud and cloud-to-ground lightning. It has been found that the stepped and dart leaders for both types of lightning radiate electromagnetic energy that is characterized by a frequency band that centers at 150 kHz. The techniques involved in obtaining these results can now be employed in the study of other types of discharges, namely the flare, tornado pulse generator, and cloud-to-ionosphere discharges.
