Skylapse.org: 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."

Purpose

The skylapse.org blog is a collection of video embeds, animated gifs, and other illustrations that reveal atmospheric features that may be normally subtle or elusive in real-time, but come to life when the time-lapse technique is applied. The sole intention of creating the blog was to generate a library of ready-to-use visual atmospheric illustrations for pedagogical purposes. While some of the imagery in the blog is my own, most are derived from video sharing sites and, subsequently, embedded or hyperlinked. Please use the "labels" feature below to quickly find examples of phenomena.
