radarman Posted 6 hours ago Share Posted 6 hours ago Ice fishing in Ludlow in a low torchy spot... ice is 16". Up in the higher more protected terrain it's gotta be 2 feet I bet Link to comment Share on other sites More sharing options...

Biggest I can ever remember. Wish I could post the video, but too big size. Here’s a screen grab… much easier to see the definition in the video but that’s like a 1,000ft tall vortex.

Dust devils rely on hot surface temps…snow sfc temps are relatively cool because of the albedo. Since they’re often on mtns…I’m going to guess they start as a local swirl/vortice that strengthens as it slides down in elevation as it stretches vertically and tightens and speeds up like a figure skater. 2 Link to comment Share on other sites More sharing options...

They seem to start during differential heating or steep lapse rates during CAA. We seem to get them during times of broken clouds/partly sunny conditions after a snow, with a strong 850 mb flow amid steep low level lapse rates.

dendrite Posted 2 hours ago Author Share Posted 2 hours ago I guess I’m just having trouble understanding how you’re getting that strong of sfc lapse rates and differential heating aloft on the mountain side snow surface. Do you get whirls like that during warm season? Link to comment Share on other sites More sharing options...

Do you get whirls like that during warm season? Not visually at least during the warm season… but I don’t think we get them. It seems to be a phenomena that occurs in a strong low level flow with a big thermal difference in the lowest 5,000ft. 30F in the valley, 10F up top. Some destabilizing sunshine. They seem rare when it’s completely thick clouds. I think that’s what I think of when I see them… it’s a well-mixed atmosphere. Link to comment Share on other sites More sharing options...
