Von Karman Vortices with a Pair of Rainbows

From New Scientist:

" The layer of stratocumulus clouds normally reflects a portion of solar energy into space and in this image the clouds are diffracting the sunlight back to the satellite splitting the light into its constituent colours.

...Von Karman vortices are linear series of alternating spiral eddies formed by a fluid moving round an obstacle, in this case it is the clouds moving around the island.  "
