A lightning strike or lightning bolt is a lightning event in which an electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning.
One can tell where lightning will strike within a mile radius by measuring ionization in the air to improve the accuracy of the prediction. To understand this aspect of lightning detection one needs to know that a lightning 'flash' generally consists of several strokes, a typical number of strokes from a CG flash is in the range 3 to 6 but some ...
Positive lightning is less common than negative lightning and on average makes up less than 5% of all lightning strikes. [10] A bolt from the blue lightning strike which appears to initiate from the clear, but [clarification needed] the turbulent sky above the anvil cloud and drive a bolt of plasma through the cloud directly to the ground. They ...
A lightning prediction system is a type of lightning detection equipment that determines when atmospheric conditions likely to produce lightning strikes and sounds an alarm, warning those nearby that lightning is imminent and giving them the chance to find safety before the storm arrives in the area.
The danger of a lightning strike depends on several factors, including where a person is when being struck, the kind of object someone is holding or even the amount of water on the person's skin ...
Antenna signal of a lightning strike over one millisecond. The strike was registered at .0005 seconds (500 μs) Example for determining the location of a ship using 'hyperbola navigation' The stations continuously digitise the low-frequency signals from the antennas in the range from 3000 to 30000 Hz with a sampling rate of over 500 kHz.
Global map of lightning frequency--strikes/km 2 /yr. The high lightning areas are on land located in the tropics. Areas with almost no lightning are the Arctic and Antarctic, closely followed by the oceans which have only 0.1 to 1 strikes/km 2 /yr. The map on the right shows that lightning is not distributed evenly around the planet. [5]
