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.
Single sensor lightning detectors have been used on aircraft and while the lightning direction can be determined from a crossed loop sensor, the distance can not be determined reliably because the signal amplitude varies between the individual strokes described above, [11]: 115 and these systems use amplitude to estimate distance. Because the ...
These flashes usually begin as normal IC lightning flashes before the negative leader exits the cloud and strikes the ground a considerable distance away. [10] [11] Positive clear-air strikes can occur in highly sheared environments where the upper positive charge region becomes horizontally displaced from the precipitation area. [12]
We walked into the house about 8:30 at night. It was almost dark – not completely – which perhaps was why we didn't notice that the lights weren't operating at full strength. The floor ...
The view from Malibu, California, as a early morning monsoon storm moving north up the coast created a huge lightning show that could be seen from Orange County to Santa Barbara County on Friday ...
Teague, Texas, was named the lightning capital of the U.S. with over 1,900 occurrences of lightning per square mile in 2024, according to Vaisala, a global technology company.
Time of arrival (TOA or ToA) is the absolute time instant when a radio signal emanating from a transmitter reaches a remote receiver.The time span elapsed since the time of transmission (TOT or ToT) is the time of flight (TOF or ToF).
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]
