Just checked the link, nice pics. I like the most the cirrus one with the halo. But I am surprised nobody noticed the relatively rare cloud punches in the two cirrocumulus pics.
Hi Hilary from Toronto and welcome, I would not call myself an expert, but I have a bit of experience and I would gladly look at your clouds. So I will send you a mail at the address you gave us. Just so that you know where I am coming from.
I think it was done from another airliner flying in the opposite direction in the same corridor. Vertical separation between airplanes is only 1000 ft (considered too little today by many, but that’s the practice). I think there are cameras under some airplanes these days that entertain passengers, so the shot from above is possible.
The humidity conditions seem to have been right. The sky is full of what looked like decayed contrails.
So if I could quantify my level of trust, I’d say 90%
Incredible beauty. I liked everything, but one thing I really had to stop and go backto see again was the night shot where you can see the Milky Way above and a storm in the distance.
Here is more “land art” by Turrell:
See the Spaces tab. There are some traces of clouds, but the focus is “celestial”.
I’ve been to Phoenix (actually Scottsdale) in the Summer. I think it’s the misters. Restaurants and other places spray a fine mist that by evaporating should cool the environment. I couldn’t tell, went inside anyway. (I still like it over there.)
(I had problems logging in in early April, same as Graham. “Support” advised me to clear browser cookies, which I did, though only now. If you see my post, it worked. Or maybe there was some server problem that got fixed.)
Catching up on this thread …
Hans, I don’t think your last shot is iridescence, maybe section of a halo, which would be rarer. Or sun dog? Very nice.
Now, I did buy the camera I mentioned a while back. I got a Sony alpha 6300. And for telephoto, a 50-210 mm. I think that’s enough to start. It’s amazing what a telephoto can do. And the 24MPix helps too. A couple of shots, with some enhancing.
Samuel,
The general explanation is that mammatus are caused by sinking air. With the intense convection in a cumulonimbus cloud is, there has to be some downward air motion.
The page below says that the mammatus appear typically after the storm has passed. So if a tornado did not occur, you would be safe.

But in the diagrams in this Wikipedia article, I see mammatus both ahead of the storm and behind:

So there you have it :-)
The Azure Window collapse reminds me of another mourned natural formation which meant a lot to people, the Old Man of the Mountain in New Hampshire.
Simply amazing skill and cooperation.
And, not sure if you noticed, some optical phenomena. At 0:10 precisely, a circumzenithal arc and at 2:55 a sun dog. Did no watch the full video, maybe there is more, conditions seemed good.
I am happy to see a generally overlooked landmark, the Unisphere, in Queens, the borough of New York City where I live. I bike there where the weather is nice. Should plan to take some UP pictures.
Here are some contrails, that I think are just smoke. This is the photo of the day in the CloudStream. Notice the first first three airplanes don’t leave a trail.
Very nice shot, though.
I can’t tell what it is, but I don’t think is a fallstreak hole. In a fallstreak hole, the ice crystals that form tend to precipitate and evaporate, so upper part is thicker and the lower part is fading away, like in a virga. Here it seems that the falling stuff coalesces in one long thick cloud. Unless, it’s the other way around, where the “ribs” are actually going down, but to me their curvature indicates that they are going away and up.
Jean-Pierre, do you have other shots of this phenom, either other angles or how it evolved in time, before and after?
