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.
Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit.
The Earth is struck by lightning nearly 20 million times each year, and bolts of lightning can travel as much as 10 to 12 miles from a thunderstorm, instantly heating the air to 50,000 degrees ...
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.
Similar to the famous Miller-Urey experiment in 1953, the team simulated the conditions of early Earth in a laboratory, and studied the chemical reactions when simulated lightning strikes struck ...
When seen from Earth, lightning appears both powerful and majestic, but when viewed from space, it can seem a little ghostly. Astronaut spots 'spooky' lightning on Earth from space Skip to main ...
The lightning that triggered it was in Polverigi, AN, Italy, at a distance of 285 km. Its strength, estimated at about 410 kA (kilo-Ampère), which is an order of magnitude stronger than a normal lightning (10 to 30 kilo-Ampère), generated an intense electromagnetic pulse. The red ring marks where the pulse hit the Earth's ionosphere.
A return stroke, cloud-to-ground lightning strike during a thunderstorm. Cloud-to-ground lightning frequently occurs within the phenomena of thunderstorms and have numerous hazards towards landscapes and populations. One of the more significant hazards lightning can pose is the wildfires they are capable of igniting. [54]
