A lightning strike or lightning bolt is a lightning event in which the 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.
Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type.
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.
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 ...
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.
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 ...
This gives Lake Maracaibo the highest number of lightning strikes per square kilometer in the world, at 250. [6] The region with the second-most is the village Kifuka, in the mountains of the Democratic Republic of the Congo, [7] where the elevation is around 1,700 metres (5,600 ft), receives 232 lightning strikes per square kilometer (600 per ...
The National Lightning Safety Council (NLSC) announced this week that 13 people were killed by lightning in 2023, the second-lowest number since 2001 and well under the 10-year average of 22. The ...
