Sometimes natural phenomena mixed with technology can produce interesting results. I found this picture accidentally. But, it is so stunning to me that I had to share it.
The attached picture was taken of one of Vattenfall's at-sea wind farms.
The wind turbines are huge and the wake turbulence is usually invisible...unless a vapor cloud forms, as has here.
NOAA has a higher resolution picture here if you want to see more detail:

It happens with any obstruction placed in an air stream...such as filter membranes or jagged steps in an engine intake tract.
Still, I just like the picture for aesthetic reasons. I'd like a poster for my wall...
Hope you enjoy it!
