There's a mesmerizing new project from an organization called Blitzortung.org that lets you see real-time lightning strikes around the world. It works using a network of volunteers willing to ...
Lightning is a natural phenomenon, more specifically an atmospheric electrical phenomenon. It consists of electrostatic discharges occurring through the atmosphere between two electrically charged regions, either both existing within the atmosphere or one within the atmosphere and one on the ground, with these regions then becoming partially or wholly electrically neutralized.
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]
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.
Lightning strikes growing in the United States. Vaisala Xweather, which tracks lightning, is tallied just over 242 million bolts of lightning in the U.S. in 2023. The company tells USA TODAY that ...
New data shows Texas saw the highest number of lightning strikes in the U.S. last year.
Lightning strike counter in a Museum Patio. Inexpensive portable lightning detectors as well as other single sensor lightning mappers, such as those used on aircraft, have limitations including detection of false signals and poor sensitivity, particularly for intracloud (IC) lightning. Professional-quality portable lightning detectors improve ...
The flash of a lightning strike and resulting thunder occur at roughly the same time. But light travels 300,000 km/sec, almost a million times the speed of sound. Sound travels at the slower speed of about 340 m/sec (depending on the temperature), so the flash of lightning is seen before thunder is heard.
