The Vortex: Roll cloud over Lake Michigan

My corner of Northern Michigan was all abuzz last weekend due to a relatively rare meteorological phenomenon known as a “roll cloud.” Wikipedia’s entry on Arcus clouds explains:

An arcus cloud is a low, horizontal cloud formation. Roll clouds and shelf clouds are the two types of arcus clouds. A shelf cloud is usually associated with the leading edge of thunderstorm outflow; roll clouds are usually formed by outflows of cold air from sea breezes or cold fronts in the absence of thunderstorms.

…A roll cloud is a low, horizontal, tube-shaped, and relatively rare type of arcus cloud. They differ from shelf clouds by being completely detached from other cloud features. Roll clouds usually appear to be “rolling” about a horizontal axis. They are a solitary wave called a soliton, which is a wave that has a single crest and moves without changing speed or shape.

Regular Michigan in Pictures contributor Shawn Malone of Lake Superior Photo created the official music video for David Helpling’s “As The World Falls Away.” It features her latest cinematic time-lapse work filmed entirely in the Upper Peninsula of Michigan merged with sequences from NASA’s ISS to form a stunning visual & auditory journey.

It will appear on the The Weather Channel in their “Weather Gone Viral” episode that airs tonight on The Weather Channel. She says they’ve told her 10 PM EST, but check your local listings.

and then I saw this cloud…

Manitou Stormcloud and the Earth Science Picture of the Day

One of my favorite photoblogs is the Earth Science Picture of the Day (EPOD), and sometimes you’ll see photos from Michigan in Pictures there and vice versa. The EPOD is produced by the NASA Earth Sciences Division, and every day their stalwart blogger Jim Foster works with photographers all over the planet to highlight amazing things. In June the EPOD posted a cool photo of a roll cloud over Calgary, explaining:

Roll clouds are a type of arcus cloud often associated with turbulent weather. As is the case here, they sometimes look like a horizontal tornado. Although these cylindrically shaped clouds look quite fierce and may be observed to roll about their horizontal axis, they don’t usually generate dangerous winds. Roll clouds are typically found behind outflow boundaries but unlike shelf clouds are detached from any close-by cumulonimbus cloud.

I know that I featured a photo from Shane last Thursday, but this one was just too cool to hold back! Check his photo out bigger and see more in Shane’s slideshow.
