Lightning is one of the major causes of bushfires, particularly in the remote mountains. This lightning detector system was developed by Dr. Peter Kourtz at Canada’s forest fire research institute. By 1977, some 300 were in use across the country. The small mushroom antenna could detect short-range (20-mile) changes in electrostatic field associated with lightning strikes. It needed to be placed out in the open on a hilltop and away from nearby trees. It simply counted the number of "strikes". The detector doesn't seem to have a direction finding capability or be able to distinguish between cloud-to-cloud or cloud-to-ground lightning. It's not sure how this particular unit found its way to Victoria. The Bureau of Meteorology's (BOM) current lightning detector network uses radio waves emitted by lightning to pinpoint the location of lightning strikes. The network is operated by a private company that sends data to the BOM in real time. Lightning detection systems use sensors like antennas, GPS receivers, and processing systems to detect radio waves, also known as sferics. The systems calculate the lightning's location and speed by measuring how long it takes for the radio signal to reach the different antenna stations. The BOM also has a Thunderstorm Tracker that uses weather radar data to identify areas of potential thunderstorm activity. The tracker updates every six minutes and shows the direction thunderstorms are moving, as well as their expected position in 10, 20, and 30 minutesLightning detector 1970sQ-Techforests commission victoria (fcv), weather, bushfire, bushfire aviation
