And doesn’t lightning move from the ground up?
Depends on you point of view..................
I recall reading that the path for the lightning rises up and the lightning then follows it.
Yes it does. That’s one thing I learned in the airforce and actually retained.
An upward moving streamer of charge, usually positive, rises from a grounded object toward negative polarity step-leaders extending from a charge concentration within a cloud. The streamers are rarely perceived or caught on camera.
