Skylapse.org: 17 October 2012 NIU Hole-punch Cloud

The NIU webcam system captured a hole-punch cloud as it formed and moved east on this beautiful October day. Hole punch appears at 30 sec mark. For a scientific explanation of these events, check out this BAMS article.

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.
