Kelvin Helmholtz clouds

Pie · 10-21-2009, 03:28 PM

So, I saw this cloud phenomenon as I was driving home to let the dog out. "Wow," I said to myself, "those look like Kelvin Helmholtz clouds!"

There are, of course, many better examples of this type of cloud. But it was still a thrill to see one in the wild. Here's my phonecam pic...

Excellent, Pie. To actually see that, and get us a picture too, good job.

Very well spotted, Pie. And great photo - there are far poorer examples out there, from people who do this kind of thing professionally.

Aha, yes, case in point.

Pie is officially an uber-nerd. A good thing, Pie; a good thing! very cool! There is an international Cloud society - you know about them?

I do now! Thanks, Bri.

How scary would it be to see these guys?

If it makes the cut, asperatus will be the first new addition in more than 50 years.

Them clouds in Iowa looks like serious tornado weather to me.

Tornadoes my foot.

The forecast for today is fine in the morning, with divine wrath beginning in the early afternoon, with a chance of apocalyse later in the evening...
