I captured this awesome cloud during a short family holiday in Northumberland last week. I like it a lot.
I guessed it was cumulus congestus but checked with Gavin Pretor-Pinney of The Cloud Appreciation Society:
“Yes, indeed. With a crisp summit like that, it had yet to mature into a Cumulonimbus, at which point the top freezes and looks more blurry. It’s a beauty.”
Feel free to use the larger version for presentations (or whatever).
What a fabulous picture, Steve! May I use it as my PC desktop picture, please? I realise as a Mac user you may have to think for a moment!!
Thank you, Nick. Of course. Grab the larger version from Flickr!
