Those giant waves—"undular bore waves"—were 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.
Undular bores are a type of "gravity wave"—so called because gravity acts as the restoring force essential to wave motion.
