Steam Devils

Steam devil season is underway. In late summer-early fall when waters are still warm but morning air is growing cold, little tornadoes of steam are often seen dancing across lake surfaces.

Iowa photographer Mike Hollingshead caught this one at sunrise on August 29th.

Steam devils appear when vapor released by a warm lake condenses rapidly in cooler air above. Light winds spin condensing plumes of steam into dancing columns. The bigger the lake, the bigger the devils.

Steam devils on Lake Superior have been observed to rise 1500 ft tall!

Excuse me, but why exactly did you opt to chop off my copyright notice listing my website on these?

They came from this site and page:
http://www.extremeinstability.com/08-8-29b.htm

They were listed on spaceweather with that text. Neither place had the copyright notices removed. Please take them down now if you feel the need to remove my site url while placing them on yours.
