These images from Earth Observatory show islands creating ‘von Karman vortices' in the stratocumulus clouds. In the animation you can see that each vortex is formed from alternating sides of the object that is impeding flow of the fluid such as clouds or soap films.

In the first image, the water droplets in the clouds create an optical phenomena known as Glory, making the rainbow to the left. However, this is different from a rainbow, in that it is formed from backwards diffraction meaning they are always directly opposite to the Sun.
