Kelvin Helmholtz clouds

1 Attachment(s)

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...

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.
We've said we'll miss you if you go - keep your eyes in the road lady!

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

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...
