- Scud fragments below a storm mesocyclone dance in a circle
- W001374Z
- Close view of moist outflow air drawn into the mesocyclone rotation of a supercell storm. It rises and condenses as scud in mid-air, then joins the base. Condensation occurs at a level lower than normal because the air, moistened by rain, has a higher dew point. At left, the circular structure is visible in the curved scud edge but is compressed by perspective. All the scud fragments dance in a circle like a slow merry-go-round.
