Kelvin-Helmholtz Billows

[Guest pelorus32]

This is not the best photo ever but it does show you what a K-H billow cloud looks like. They happen often in high winds at the shear layer between two opposing airflows.

What's in a name?

 

Mike, I'm wondering how I managed to fly for 49 years and NOT know the name of THAT cloud. I probably covered it by saying something like " If you fly near them clouds with the curly ends it might be a bit rough ". (sigh) so MUCH to learn.. Nev...

Ahh Nev,

 

I suspect that like you I've decided that it doesn't really matter....It's an interesting curiosity though isn't it?

 

There is a nice literature about these clouds and the dynamics that create them. I'd stumbled across them when looking for something else, become engrossed...and then a couple of days later I looked out the window and here one was.

 

I suspect also that they are a newly described curiosity - say the last 10 years or so.

 

A mild distraction from the pre-Xmas cr*p.

Whether weather?

 

Mike, A fascination with weather is a good sign. It acknowledges the fact that you need to understand the element you occupy. Nev

Mike,

 

Ive seen those a few times around here over the past couple of years -and I could never find out what the bloody hell they were called, or the process that made them.

 

Thanks for that.

 

Ben
