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.
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.
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 ...
Schumann resonance is due to the space between the surface of the Earth and the conductive ionosphere acting as a waveguide. The limited dimensions of the earth cause this waveguide to act as a resonant cavity for electromagnetic waves. The cavity is naturally excited by energy from lightning strikes. [27]
There are about 40,000 thunderstorms per day, generating roughly 100 lightning strikes per second, [1] which can be thought to charge the earth like a battery. Thunderstorms generate an electrical potential difference between the earth's surface and the ionosphere, mainly by means of lightning returning current to ground. Because of this, the ...
Consequently, the current from a strike merely "passes" through the wrapped tube, through the wings and leave the plane. h/t Lonely Planet RELATED: Foods you should never eat on an airplane
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 ...
