As a result, as a lightning channel travels through the air, ionization occurs, forming deposition.
2.
The visible part of a lightning channel has a typical length of about 5 km.
3.
Since lightning channels carry an electric current to the ground, lightning can produce magnetic fields as well.
4.
This excess charge is transferred to the ground via lightning channels, which carry a strong electric current.
5.
These discharges have peculiar features : velocities of and plasma temperatures of are achieved in nanoseconds in lightning channels.
6.
He said that while the lightning channel process is not fully understood, it is a " very random process ."
7.
Some, like the one that hit your house, have a longer-duration flow of current within the lightning channel that can start fires.
8.
Lightning discharges are considered to be the primary natural source of Schumann resonance excitation; lightning channels behave like huge antennas that radiate electromagnetic energy at frequencies below about 100 kHz.
9.
The steady electric discharging currents in a lightning channel cause a series of incoherent impulses in the whole frequency range, the amplitudes of which decreases approximately with the inverse frequency.
10.
In a positive-to-ground lightning strike, positive charges first rush from the cloud to the ground, creating a lightning channel through which electrons flow from the ground back up to the cloud.
