- Cloud edge lacination in a lee wave pattern and wave crest
- W882322Z
- View to the west of a lee wave pattern and cloud edge lacination. Clouds over the mountains evaporate as air descends the slopes, but a new cloud forms when the air rises in the wave crest and condenses again. The chaotic, lacinated cloud edge suggests turbulence. Cloud elements begin as supercooled water droplets that freeze quickly downstream.
