Lightning Upward Streamers

We've learned about negative charged lightning leaders, and how they are ionized gases going down toward the ground looking to zap something.

Sometimes there are positive charges on the ground that are going up looking to get zapped.
These are called upward streamers or upward leaders.

If there is a positive charge on the ground, it will reach out from the tallest points, either a tall building or a tree top, reaching up to the downward leaders.
If the two connect, there is a huge lightning zap!
