Below your see a smoke plume going up out of the ground.
Explanation: the copper (anti lightning) wire along the pole has heated up the ground below which exploded with brown sand color.afterwards it becomes white seemingly because of steam from heated water in the ground.
Conclusion:
the electric power of the ball lightning is heating up the wire enough to do the smoking job.
