I couldn't venture a guess as to the cloud that looks like a smoke ring, but the first one, the original post is a fairly common occurence here in my
neck of the woods. I can't remember the name of it either, but you see this when there is very unstable air above you.
I remember exactly where I was the first time I saw it and since then I have seen it many times. I guess I had just never noticed it before.
The OP is correct in associating that with tornadic activity. It is common during extremely volatile upper and lower level air masses colliding. It
looks like the plasma scenes in Ghostbusters. Very cool to look at. I have some pics of it around here also (probably can't find them though, as I
have thousands)
Edit - I just read the above poster's link on mammatus clouds and I wanted to clarify that I didn't mean that if you see them, there is about to be
a tornado, just that you are looking at a volatile system.
