Positive CG Lightning
Tom Warner captured this positive cloud-to-ground lightning flash with a high-speed camera -- recorded at 7,207 images per second! As he states: "Weak positive leader branches decay and become cutoff as they propagate downward from the cloud. Fast recoil leaders develop along the decayed branches in an attempt to reionize the branches. The downward positive leader eventually connects with the ground forming a bright return stroke."
