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 ...
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.
Before the lightning strikes earth, the filaments lead electricity through the clouds, playing the role of lightning rods. Researchers generated filaments that lived a period too short to trigger a real lightning strike. Nevertheless, a boost in electrical activity within the clouds was registered.
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]
How many volts are in a lightning strike? A typical lightning bolt carries about 300 million volts and 30,000 amps, according to the NWS. Compare that to the typical household's electric current ...
Here’s how to stay safe when lightning strikes. When thunder rumbles, lightning isn’t far behind. About 25 million times a year, lightning strikes the United States, according to the National ...
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 ...
Lightning injuries are divided into direct strikes, side splash, contact injury, and ground current. [1] Ground current occurs when the lightning strikes nearby and travels to the person through the ground. [1] Side splash makes up about a third of cases and occurs when lightning strikes nearby and jumps through the air to the person. [1]
