- W953106S
- A very complex, undulating wave pattern flows over a group of towers in a storm, showing as several Pileus clouds. The bent layer must be quite moist, since it is thick and shows all the slight changes in flow angle. While the parts against blue appear bright, the cloud at lower right is dark against the storm, suggesting that it is less dense.
