Clouds never stay still. They’re in a state of perpetual transition, mutating from one form to another. This ephemeral, ever-changing quality is part of their beauty. If you have time-lapse video of clouds for this page, upload it to a video hosting site like Vimeo or YouTube and send us a link.
Bobby Coggins, member number 12680, sent in this time-lapse clouds video. He wondered whether this is an example of asperatus clouds. We think that it looks more like a sky of lacunosus and mammatus clouds. Either way, we like the dramatic effect.
