Welcome Skywatchers!
I'm glad to announce that we have an addition to our team! Louise is joining the team of Skywatch and MyWorld! Give her a warm welcome!
And - like in MyWorld - we added the Followers Gadget at the bottom of each page - to make it easier for you to keep track of Skywatch!
But now I hand over to the dweliciously knowledgeable DewDrops - our Sky Goddess for another of her great Sky lessons!
Time for another post for the Skywatch 101 Series...
Here's lesson five. I have chosen a pyrocumulus cloud that I captured from an airplane as we flew by a fire on the ground.
Pyrocumulus Clouds
A pyrocumulus cloud is produced by the intense heating of the air from the surface. The intense heat induces convection which causes the air mass to rise to a point of stability, usually in the presence of moisture. Phenomena such as volcanic eruptions, forest fires, and occasionally industrial activities can induce formation of this cloud. Pyrocumuli contain severe turbulence which also results in strong gusts at the surface which can exacerbate a large conflagration. Large pyrocumuli can contain temperatures well below freezing, and the electrostatic properties of any ice that forms may also play a role. A pyrocumulus which produces lightning is actually a type of cumulonimbus, a thundercloud and is called pyrocumulonimbus.

Happy SWF to all :-)))
I know I'm repetitious but I so enjoy your instructional posts. Besides the information, this cloud looks so much like cotton that against another background I'd be sure it was a big cotton ball mass. Beautiful.
nice.. i love the sky and the clouds looks like cotton candy... yummy... you can also visit mine through HERE
Hi to the team,thanks so much for what you do here... Hi to Louise, welcome here and DewDrops thanks so much for the info on the pyrocumulus clouds, I always find it so much fun to learn about clouds and their names as I have loved the sky all by myself for so long, my whole life and NOW we can all love the sky together....
Great SWF photo!!!
Hi and good morning, here it is a wonderful day for SWF. Great shot from the plane. I learned to recognize a new cloud,thank you for the info. Thank you for SWF and all the work you do. Have a nice SWF.
Wonderful picture and thanks for the write up too.
I also thought that I could see a face in there.
Great news too that Louise has joined you. Well done Louise.
Thank you to all the team for making such a great site available to visit and share around the world views.
Great clouds, looking forward again for skies all over the world
Niiiice shot!
Well, now that I know what it is, I hope I don't fly close to any of these clouds. Thanks (I think), for the lesson, Dewdrop.
Great picture.
What a shot. great capture.
Mine is here too.
Dwdrops explanations are fantastic. I
am celbrating bonfire night with lots of fireworks.
Just how beautiful can you get? And the information is fantastic.!
My giggle, this "Pyro" thing, I just had a "Pyroclastic granduloma" removed from my inner lip. Ya know, it kinda looked like this coud! :D Happy SWF.
Great cloud and an interesting lesson. Thanks :-)

Great photo - they are certainly some spectacular clouds!
My contribution for Sky Watch is up and for a change - I'm a little earlier than normal - *grin*
As usual, if you do stop by, I'll be sure to return the favour too!
We're back at Bondi in Sydney this week. Hope you like it. I'll try to visit where I can but it's a busy day (and my birthday!)
Learned about the cloud name in Geography subject and it was 16 years ago. Couldn't remember it's name anymore.Thanks for this revision and great shot.
Thank you DewDrop for picking up the slack here. I have enjoyed your lessons and try to fit my collection to your topics. I don't do so well along those lines.
This is a pretty cloud, I have quite a few taken from the plane, they are so pretty viewed from the top and sides.
..
Your cloud picture is very nice. I have not had a cloudy day lately.
here is the link to my sky
pictures.

Really interesting to learn more about what makes up pretty puffy clouds and the science that makes the weather that produces lovely veiws that we enjoy. Thank you for sharing with us all.
Interesting lesson, and Louise is a great addition to your team.

"Louis la Vache" is on board this SWF with an exclamation point!
The big fluffy ones are some of my favorites. I love the whipped cream look. Great capture!
Amazing! Hard to believe that picture was taking through the window of a plane.
Thank you so much for another wonderfully informative post, and an exceptional photograph.
Congratulations, Louise! Another great lesson and photo, Dewdrop!
I love, love, love clouds - of all shapes and sizes and all kinds :-D
I actually thought I was going to be a little 'earlier' on the list, since it's still Thursday night here... but I was wrong... I'm still in the mid-200s. hehe What a truly magnificent meme this is - I'm honored to be a part of it.
Happy Sky Watch everyone, and I hope you have a wonderful weekend and hope to see you at Camera-Critters!

Skywatch is one of the motivating factors in my starting a blog, just so I could join you. I don't have the link thing figured out yet, but I am still working on it. Hey, it has only been 4 days!

lots of interesting skies here from all over the world!
Posting my first Skywatch...thanks for having me!
The things one learns in blogland eh?
Thanks for the great pic and the info.
To be less scientist, I see a Mr Potatoe Head. Maybe I kept a children mind. Very particular cloud. If I could find this specimen in my French SkY.....
Another great Friday sky!!
AWESOME photo as usual:)
Why you are judging me doing a commercial i just accept a little bit of it and not accepting bad adverts... My blog is not making a lot of paid post or anything... Why you will not check all your participants i am not only the one making or accepting commercials. This is cruel it hurts my heart. If you delete this its ok at least i express my feelings that hurts and its me cry. I enjoy joining this group because i love taking pictures. If i do something wrong i am sorry but its a mistakes. This makes my day bad... sorry... bye

I haven't read through all the comments, but did anyone else think that cloud looks like the Grinch?

Very cool looking cloud. Kind of has an evil grin going. Happy Skywatching.
Later than planned, but mine is up. Hope you will stop by. I am continually amazed how this list is growing and there are SOOO many great Sky Watchers out there!
Stop by my place if you get a free moment, and say HI!
Amazing shot! Pyrocumulus clouds? I don't know if I can identify them in the sky! :)
That's quite a formidable cloud formation! I like that you included the explanation along with it.
Recently I did a post about "Burning the Slash" that had both some and some smoke generated clouds in it. Since the fires were small they didn't produce anything like this monster cloud. - Margy
thanks for this space :)
