There is some type of phenomena that I see over and over again in our skies – and it is always fun to watch (and quickly fleeting)! Tips of clouds often start “rolling” in the direction that the cloud is moving, forming what looks like a KH cloud, but then going on to form a circle. It kind of rolls on from there and dissipates and another roll will start – or there can be more than one at a time. I have done short videos of this and they only last a few seconds. Here is a cloud that is forming kind of like that, with some tiny little curls, too. The second image was a bit more unusual with what looks like three circles in one cloud. The color versions of these would show a blue sky behind them, but it was a day with a lot of clouds moving rather quickly. I don’t think these were very high, so are they small cumulus clouds drifting in the wind? And when they form the hook first and then a circle is that just part of clouds changing or does it have a name. The first one looks like KH to me, but I know that true KH clouds are rare and I see these on a regular basis. Thanks for the help!
This was what looked like a diverse sky and I wanted to try to name all of the various clouds. I am hoping I got just one right, LOL!! I wrote on each cloud what I THINK they are and the page in the handbook that I found it. Input and corrections very welcome! The clouds were pretty far in the distance, so the height of the trees may be misleading.

Thanks so much, Michael!! That is a lot of information to study!! I am not getting notifications when there is a post here, and I often forget to check unless I do get those notifications, so I am late in replying! Clouds are so incredibly complex, but fascinating! I can see how it is very helpful to know how they develop and what the air conditions are when they are seen.
Thanks again! I am adding a new image and I will try to remember to check back on this one!Ramona
I am posting this in both color and black and white. It has quite intrigued me. I believe it is an Altocumulus lacunosus? Is that correct?Thanks!
Ramona
Thanks, Hydde! There is so much to learn! I am trying to take it slow, but there are some clouds that just intrigue me and I skip ahead to try to identify them. I am going to post one that I have looked for throughout the ICA and I THINK I have identified it.

I have searched quite a bit for these and as near as I can tell they are Cirrocumulus? If they were Altocumulus they would have shadows on the bottom of them? And why do these get you 40 points in the “collection”? Just curious, LOL!!Corrections always welcome!
Thanks again!
RamonaHello Hygge! I have my handbook now, but I am wondering if I have a different version than yours? In my book pages 104/105 are a photograph of cloud iridescence and 29 is about Nimbostratus? However, having looked on page 29, I noticed that the next page was about Cumulonimbus and the photograph looks like something I saw last night! I had not seen it before and this one is much smaller, but it has the “hairy” look of the larger cloud in the book.
When I read the Cloud of the Day description today it brought to mind this rainbow and clouds that I photographed last week. It was quite a strange situation. I was inside and I suddenly felt like “it was yellow outside – very yellow”. I don’t know how to explain it, as it was quite an odd feeling, but I figured I would check it out. Things did indeed look very yellow outside and I saw one of the most vibrant rainbows that I have ever seen! I suspect it had something to do with the sun going down and the water droplets in the clouds? Am I on the right track? The description in the cloud of the day email was talking more about greenish clouds, but I am wondering if this would have a similar explanation? Here is what was in the email:
. The very smallest among the distribution of droplet sizes will scatter more blue light than red. This might be expected to give the clouds a bluish tinge, since this end of the spectrum would be scattered rather than absorbed by the cloud. Why then the green colour? This might relate to the time of day. Thunderclouds tend to reach maturity towards the end of the day, when the light striking their upper reaches has the warm hues of sunset. With the blue light already scattered out by the evening sunlight’s long passage through the dense, low atmosphere, a thunderstorm that might normally appear a dark bluish grey could end up appearing faintly green, especially towards the horizon.
I can’t remember exactly how long this one was there, but I think it was a few minutes rather than seconds, like the KH clouds are. I suspect it was just a coincidence, too, as this doesn’t seem like the right type of cloud or the right situation. I will keep an eye on the sky and look for others, though!!
Thanks for the help!!

I got my handbook!! What fun reading it is! I sit each evening and watch the clouds move across one part of our sky. These clouds move over a river and I am wondering if that affects the wind patterns. I know there is very little chance of this, but I was reading about the horseshoe vortex clouds and wondering about the formations I watch over and over again. Here is an example of them – the higher cloud is in kind of a horseshoe shape, but it’s way to large and probably not the correct type of cloud, right? I will post a black and white version of it, too, so the contrast can be seen more clearly. I am loving the book!!
Oh, what a wonderful idea, Hans! I ordered one from Amazon, but I know a friend who would love a copy, too, so I can give the first one to him. Do I just go ahead and order it from the shop or do you need to do something special to get it signed?
Thanks!

Wow, thanks for all of this great information, George! Yes, it was quite a turbulent day and lots to keep me occupied as we traveled! Thanks for the suggestion on the red filter – I can do that in editing and will see what effect that has. And yes, your little cloud looks a lot like mine!!
I am so glad to have you guys as resources to help me understand more and more about clouds!
Yes, the undulatus fringes on this little cloud were very small – I only noticed them on the photo after I looked at it on the computer! It was just such an odd little cloud, all by itself among the “big guys”!
And thanks for the encouragement on starting this thread! I will do my research first and then ask questions, in order to not waste anyone’s time with just throwing all of my (MANY) questions out there!
