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 ...
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]
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.
In addition, Blitzortung (a private global detection system that consists of over 500 detection stations owned and operated by hobbyists/volunteers) provides near real-time lightning maps at . The Earth-ionosphere waveguide traps electromagnetic VLF- and ELF waves. Electromagnetic pulses transmitted by lightning strikes propagate within that ...
New data shows Texas saw the highest number of lightning strikes in the U.S. last year.
Mr Reynolds, from Bow, east London, told the PA news agency: “There was thunder and frequent lightning through the early hours, then at 5.30am the storm broke overhead with an enormous crack and ...
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 ...
Side flash: When lightning strikes a taller object, like a tree, some of the current jumps to the victim. Ground current: When the current from a lightning strike travels along the ground.
