Abstract
High-speed video recordings of natural lightning flashes
show amazing details of this phenomenon. The paper
summarizes the results of the 2009 measurement campaign
where the combination of electric fields, total lightning,
high-energy detections and high-speed videos provided a
valuable data. The paper describes the visible differences
between the recorded negative, positive and upward cloudto-
ground flashes. Thanks to the precise time
synchronization of each video frame we investigated which
processes are detected by the lightning location networks
(VHF and VLF). We suggest that the VHF interferometer
network detects mostly those processes of intra-cloud
flashes where substantial charge is transferred during few
milliseconds. The study of the detections of intra-cloud
events provided by the VLF network were related to high
and fast (less than a millisecond) charge transfers within the
cloud that saturated the camera in the same manner as
return strokes in cloud-to-ground flashes. In other hand, the
paper discusses the high-energy detections related to a very
close cloud-to-ground lightning flash.
