This Strange Phenomenon In Iowa Is Too Weird For Words

In June of 2006, Jane Wiggins looked out of her office window in downtown Cedar Rapids and made a discovery unlike anything she ever expected. What Wiggins saw was a huge, wave-like cloud rolling over the city. She was so perplexed and amazed by this cloud, which was unlike anything she had ever seen. She took photos and sent them in to National Geographic, who posted them to their website, garnering national attention. Wiggins knew that this cloud was special, but what she didn’t know was that she had just taken the first photograph of a very rare phenomenon; a previously undiscovered cloud formation called the Undulatus Asperatus.

The video below is a time lapse showing the surreal, wavelike Undulatus Asperatus clouds moving through the sky. It’s truly magical to see, and unlike anything else you have experienced.

These special types of clouds are very rare, and are most often seen in Plains states like Iowa and Nebraska. They are thought to form when a Mammatus cloud is pushed and pulled by the wind, and warped into strange shapes. Most often, the clouds form around the time of a severe thunderstorm, though not always.

This bizarre cloud type’s name, Undulatus Asperatus, means “roughened wave,” and refers to the cloud’s wavelike appearance, which is somewhat reminiscent of a Van Gogh painting – starry night, anyone?
