Steam Devil Intense sunshine around mid-day on 23 April 2013 caused the rapid sublimation / melting of several inches of snow that had fallen overnight. Condensation produced a widespread layer of "steam fog" just above the moist surface of a plowed field immediately south of the CSU-CHILL radar. On several brief occasions, the intense surface-based thermal instability caused the fog layer to organize into rotating "devils". Photo credit: Pat Kennedy |
