- Duplicate layer
- Apply wind to top layer
- Put top layer in difference mode
- Layer>New from visible
- Colors>Desaturate (average)
- Use Levels to make sure the maximum value is white
- Go to the channels list and copy one of the RGB layers (just drag to the list below)
- Back to layers
- On top layer: Layer>Mask>Add layer mask, and initialize to the Channel you created.
