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.
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.
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 ...
A series of lightning strikes spidered across the New York City skyline the evening of Saturday, April 1, a few of which stretched from the World Trade Center into the clouds above in a dazzling ...
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 ...
Positive lightning is less common than negative lightning and on average makes up less than 5% of all lightning strikes. [10] A bolt from the blue lightning strike which appears to initiate from the clear, but [clarification needed] the turbulent sky above the anvil cloud and drive a bolt of plasma through the cloud directly to the ground.

Powerful footage shows the moment lightning struck the One World Trade Center in Manhattan on Saurday (1 April). The spectacle occurred after a powerful storm system that slammed the US Central ...
