A cloud to ground lightning strike begins
as an invisible channel of electrically charged air moving from the cloud toward the ground
. When one channel nears an object on the ground, a powerful surge of electricity from the ground moves upward to the clouds and produces the visible lightning strike.
Is cloud to ground lightning positive or negative?
Cloud to ground lightning is the most dangerous. The ground is mainly consisted of
positively charged particles
while the bottom of violent storm clouds have negative charged particles. Opposites attract in this situation, and lightning goes after positively charged particles.
Does lightning strike from ground to cloud?
Does lightning strike from the sky down, or the ground up? The answer is
both
. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.
What is the 30 30 rule for lightning?

go indoors
. Suspend activities for at least 30 minutes after the last clap of thunder. If you are caught in an open area, act quickly to find adequate shelter.
Can lightning go from the ground to the cloud?
Lightning is a huge electrical discharge that results from vigorous motions that occur in thunderstorms.

, within the same cloud, or between the cloud and ground. In-cloud lightning discharges are more common than cloud-to-ground discharges and are not as hazardous.
What happens if lightning strikes your house?

Is it safe to watch TV during a thunderstorm?
It isn't dangerous to watch TV during a thunderstorm
, but the electronics in a TV set are vulnerable. If you have to make a telephone call, use a mobile phone detached from its cable rather than a landline device. Over-voltages resulting from a lightning strike may follow electrical conductors into the handset.
Is lightning from the ground up?
Does lightning strike from the sky down, or the ground up? The answer is both.
Cloud-to-ground (CG) lightning comes from
the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.
Is lightning hotter than the sun?
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (
5 times hotter than the surface of the sun
). …
Is Red lightning real?
Sprites, also known as red lightning, are
electrical discharges
that appear as bursts of red light above clouds during thunderstorms.
Where is the safest place to be during a lightning storm?
