    Can someone begin to explain the actual steps at a molecular/electronic level of how lightning strikes form and "are carried through."

    What research have you done on this? What do you know already?

    indeed, I'm not going to write a whole lot of stuff only to find that either A - you already know or B - you could find in a 5 minute search on google

    I know the downward step consists of (negatively charged) electrons but the upward streamers consists of positively charged... What? No one explains that piece. No one.

    Baloney. You should not come here with both barrels blazing until you are sure of your facts. Uman explains the return stroke on pages 7 and 8 of his book. If you Google "lightning return stroke" you get 620,000 hits. Including Wikipedia. So don't go complaining to Steam King.

    Stevmg, please do some reading on the subject then if you still have specific questions on something you don't understand, then you can try to form a better thread.
