Skylapse.org: August 2011 DeKalb Shelf Cloud

As is typical with early-to-mid morning, warm-season mesoscale convective systems (MCSs) across the Midwest, they tend to be highly photogenic and feature laminar heads. I suspect this is due to the residual nocturnal boundary layer inversion and cold pool forcing air through a stable layer. This particular lapse was shot sans tripod from the interior of my car due to the stratiform rain falling ahead of the squall.

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.
