- A serrated cloud edge showing purity and perfect detail in a cloud
- W981374P
- Purity and perfect detail in a cloud. This close-up view shows a serrated cloud edge, possibly from a wave train passing through it. The original billows have been frayed by wind currents into evenly-spaced, unfrozen tufts along the edge of a high mountain wave cloud. (See wide view, W981376P.)
