Reply To: Kelvin-Helmholtz?

Dear Chris, In my opinion, you son has won the challenge. That looks like a pretty classic Kelvin-Helmholtz formation (now more formally known as fluctus). To have been an ideal example, the tops of the undulations would have had more pronounced curls to them, but...


Hi, I need some help please. My son thought he saw a Kelvin-Helmholtz just over an hour ago above Loughborough, England. I’m not convinced, but thought if anyone would know, it would be someone here. If he’s right I’ve just lost a challenge I had with...

Reply To: Castellanus on top of a contrail?

George, The online paper you found in the journal Weather has contact details for the authors.  I Googled Schultz, and I found that he’s still at Manchester University: I think it would be worth contacting him, sharing your photo with him, and asking for...

k-h, circumzenithal

It’s been a good day today. Spotted a circumzenithal ark and some distant Kelvin-Helmholtz clouds.
