Titel: Amazing steam devil video!
Beschreibung: Storm Chaser Andrew Pritchard of PrairieStormMedia.com shot this fascinating video of steam devils on Deep Lake, near Oxford, WI. Temperatures the night before had dipped below freezing while the lake water was still in the 60s, which resulted in excess steam forming at the surface. Andrew says, "Little areas of vorticity would be present as the very light winds rolled the steam across the lake surface, while little updrafts due to the instability in the lowest of levels stretches the vorticity into at times tight little circulations in the steam."
