Redditor big_mac_heart_attack Photographer David Barton snapped this extremely unusual weather event above the skies of Victoria, Australia. Apparently the unusual event is called a Fallstreak Hole (or commonly a ‘hole punch cloud’):
Such holes are formed when the water temperature in the clouds is below freezing but the water has not frozen yet due to the lack of ice nucleation (see supercooled water). When ice crystals do form it will set off a domino effect, due to the Bergeron process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud.
Not unsurprisingly, Fallstreak Holes are one of the most common cloud-related events reported as UFOs. (via This Isn’t Happiness)
The Tempescope is a novel device designed by Ken Kawamoto that displays the upcoming forecast by simulating weather conditions inside a small translucent box. The device is capable of downloading information about upcoming weather off the internet, which it then translates into a variety of modes to replicate sunshine, clouds, rain, and even lighting. Kawamoto made an early version of the device available as a free open-source project called OpenTempescope so you can try building your own, but a consumer version is planned for Kickstarter later this year. If you liked this, don’t miss The Cloud. (via Sixpenceee)
Weather photographer Mike Hollingshead, whose impressive storm photography we first featured around this time last year, has taken his editing a bit further by importing his supercell thunderstorm photos into Photoshop and setting them in motion. Hollingshead says these animations aren’t created like more traditional cinemagraphs, where moving elements from a video are isolated and the rest of the image is masked out. Instead, he uses only a static image and creates the animation from thin air. Most of the photos you see here were shot in Nebraska between 2004-2013. You can see many more examples on his website.
Filmed last month by Nicolaus Wegner in Wyoming, Montana, South Dakota, Nebraska, and Colorado, Stormscapes 2 is a gorgeous timelapse of severe weather events. Wegner deftly captured lightning strikes, rainbow formations, tornadic activity, and rolling thunderstorms in a way I’ve never seen before. Well worth a watch. (via Jason Sondhi)
Earlier this summer, storm chaser Alex Schueth managed to capture a timelapse of a rare cloud formation called a undulatus asperatus during a storm over Lincoln, Nebraska. The rolling pattern formed by the clouds almost gives the impression you’re underwater looking up at the surface at waves. (via PetaPixel)
One of six astronauts currently on board the International Space Station, geophysicist Alexander Gerst spends much of his free time staring out the window as the world zooms by 205 miles below, camera in-hand. Since arriving at the ISS in June of this year Gerst has taken tons of photographs that document hurricanes, floods, dust storms, and oil fields.
One of his favorite things to shoot are the shadows cast by clouds, something that appears surprisingly dramatic from space. Dense cloud formations can create long shadows that stretch for thousands of miles across the Earth’s surface as they eventually disappear into a black horizon. You can see new photos from Gerst daily on Twitter. (via Stellar)
