Guys, some one provide me a link to the info that states a lightning strike originates in the ground and goes to the cloud.
Everything I've read, always stated that the strike is from "cloud to ground" or cloud to cloud".
I've heard many times people argue over this "ground to cloud" theory, but I am never able to find anything that backs this up.
One more note, is the thunder we hear the air collapsing upon itself. When the bolt tears through the atmosphere, it vaporizes the air in its path, and then pushes the surrounding air outwards as it is heated up.
When the strike is done, the air collapses back together and that force of the air collapsing is the thunder.
Is that true?
Any help?
Dnk...........
