Lightning Travels From The Ground Up
The field strength between ground and cloud exceeds the breakover of the column of air.
Lightning travels from the ground up. The general direction of propagation is towards the ground but not very. Cloud-to-ground lightning starts from the sky and heads downward but what we see can travel from the ground upward. By Staff Writer Last Updated April 6 2020 A lightning bolt is created from the ground up and also down from the sky.

Now is it possible that during a lightning strike extra voltage from the lightning travels up the earth or ground wire to the mains outlet and to any equipment connected to the mains.
Negative strikes make up about 95 per cent of cloud-to-ground strikes. We still lack full knowledge about these forms of lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air called a channel.
A purely natural upward-moving ground-to-cloud lightning stroke is actually a rarity. A typical cloud-to-ground flash lowers a path of negative electricity that we cannot see towards the ground in a series of spurts. Ground current is responsible for killing many farm.
It descends to the ground in steps each about 50 yards about 46 meters in length. Lightning is caused by electrical charges in the atmosphere. First the base of a cloud sends down a little electric discharge called a stepped leader.
These lightning types are known as red sprites elves and blue jets. Lightning is the breakdown of the insulating property of air. Positive lightening travels in reverse by going from the ground up into clouds.
