First of all, Happy Memorial Day to you all.
Secondly, my wife Diane and dog Stanley and I were out for a walk at a local city park in Lincoln NE. We were walking by the lake enjoying the sunshine and feeling the light winds coming in from the east.
All at once, there was a brief gust of wind and we saw going out onto the calm waters of the lake a spinup on the water. I immediately recognized it as a "dust devil", but there were no dust, no debris associated with it. The water ripples clearly showed a circulation of the air above it.
What was even more amazing was the circulation was going CLOCKWISE :shock: !! It kept up its circulation until it went about 25 yards offshore where the waves of the lake broke up the circulation.
I figured the temps was rather cool early in the morning due to cloud cover. Then the sun came out and warmed up the grassy area east of the lake. The light wind from the east carried the dust devil from the warm grassy area onto the cool waters of the lake.
Which makes me wonder? Has anybody ever seen a anti-cyclonic dust devil? How is that different from the regular dust devils that we usually see??
Anyway it was really cool that we were there just at the right time to observe a weather phenomena. And nobody else in the crowds at the lake noticed the difference. Would have been something else if it was a huge F-0 size!! :shock: LJK
