I took this photo in the Strait of Luzon in 2013 looking at the Island of Bataan and the wake of clouds generated from it. Flows over topography are known to generate turbulence. Thankfully, these clouds allowed us to visualize the turbulence that nature can generate.

For size comparison, try to see if you can find a small fishing boat in the photo. I have been able to get the controls for zooming to work large resolution photos now. So you can view these panoramic photos in details.
