OK, you got the cliffs there. If there was a S-SE flow that day you might be looking at a little wave created by them.
It was 330/06.
I have seen these clouds before, years ago. Also, not related to any obvious airflow. It was a flight to Wales and there were loads of them, spread over a wide area.
What causes the unusual fine patterns in these clouds?
Magnified:
UFO invasion
What makes these?
Seems like you are getting no explanations, Peter. Well, we’re pilots, not meteorogists i guess..
How about this? One would almost start believing in UFO’s..
Last one is a Fallstreak hole
Second one in #14 looks like Mackerel sky
Thanks Xtophe!
I hope you realized that my question was a trap to catch the real meteo specialist who can guide us to the holy grail: where can we find a good clouds tops forecast! ;) I hope you live up to your reputation :)
I’m a glider pilot not a met boffin and more concerned by base than tops.
About #08, The layer of the atmosphere the lenticular are has to be stable and laminar flow for the wave to occur. So around the lenticular it will be very smooth.
The rotors are in the unstable convective layer below the wave and usually only at the first few “rebounds”
Considering the wind direction and that Peter found lenticulars all the way to Wales, it’s quite probable it was the same wave all the way.

Just so. I call it the magic carpet ride it’s so smooth it’s almost like the world is moving and you’re stationary.
I’ve never seen a Fallstreak hole, had never heard of it before post #16, but I want to see one now. I want to see it forming.
What creates the layer at the top of this fluffy stuff?
