Odd clouds

Saw these strange clouds in Lyme Regis this week, any idea what they are called and why the strange shape?

Re: Odd clouds

Makes me think of some Sci Fi film with a spaceship about to descend prior to the aliens taking over Lyme Regis.

Re: Odd clouds

There was a television programme a few months ago that showed clouds like that, but I can't remember the explanation, though I do remember it was quite straightforward. Something to do with temperature I think - but it usually is with clouds anyway!

You should be able to find others here:

Re: Odd clouds

Dave - both very interesting. I love cloud photography. A while ago I missed a book on the subject being sold on the forum. Hope you find an explanation.

Re: Odd clouds

Thanks guys. Got this explanation from another source.

"Possibly caused by wind hitting two hills and bouncing up to cause the ice to develop differently in those spots (those very high cirro-cumulus clouds are made of ice crystals) The strong wind then stopped, maybe it was just a freak gust, and the clouds drifted away with the holes still there. I am clutching at straws here but there is some basis in known cloud behavior. Strong wind hitting a hill can cause what is called a 'lenticular cloud' to form above by forcing warm air up very high where it forms a lentil shaped cloud. https://encrypted-tbn0.gstatic.com/images... I know yours are not 'lentils' but it could be caused by a similar mechanism...possibly."

Re: Odd clouds

Definitely not a lenticular cloud. It's a Fallstreak Hole, caused by a mixture of supercooled water and ice. I saw a good one above Cumbria many years ago and a smaller one since. They are quite rare.

Re: Odd clouds

There's a similar phenomena called cloud canals, i'd forgotten about those.

Re: Odd clouds

Yep, a fallstreak hole. I saw one here a couple of years ago, and the BBC were kind enough to publish my photo of it on their Autumn 2015 weather photos page. I got a bonus with the parhelion in the middle!

Re: Odd clouds

They are similar to lenticular clouds.

Re: Odd clouds

Dave
If you follow Jim Ford's link to the Cloud Appreciation Society site you will see someone else's photo of the same cloud taken on the same day as yours and it is certainly an example of Fallstreak Holes. See here. https://cloudappreciationsociety.org...photo-n-237530

An explanation of how these are formed is here.https://cloudappreciationsociety.org...understanding/

These are nothing like Lenticular clouds (Lenticular means "lens like" ).
The classical example of Lenticular clouds is those that regularly form in the lee of the mountains of New Zealand as here.
https://cloudappreciationsociety.org...photo-n-228190

The Maori name for New Zealand translates as "The Land of the Long White Cloud" and it is in the strong stable up currents of air in the waves that cause these clouds that glider pilots set altitude and distance records. http://www.stuff.co.nz/national/3155...a-world-record

Lenticular clouds are occasionally seen in the UK when stong sustained westerly winds create waves in the lee of the Welsh mountains

Regards.

Re: Odd clouds

Thanks guys. Interesting the photo over Charmouth. I knew they were no lenticular clouds, I saw one of those in the Peak District a couple of years ago.

Re: Odd clouds

Peter - Of course the NZ's call the UK as the 'Land of the Short White Cloud' but reckon we have a greater variety.
