undular bore wavesThese giant waves—"undular bore waves"— was photographed Oct. 3rd flowing across the skies of Des Moines, Iowa. These waves were created by a cluster of thunderstorms approaching Des Moines from the west. "At the time, a layer of cold, stable air was sitting on top of Des Moines. The approaching storms disturbed this air, creating a ripple akin to what we see when we toss a stone into a pond," says atmospheric scientist Tim Coleman of the National Space Science and Technology Center.
