Explanation: Why is this cloud so bubbly? Normally, cloud bottoms are flat. The flatness is caused by moist warm air that rises and cools and so condenses into water droplets at a specific temperature, which usually corresponds to a very specific height. As water droplets grow, an opaque cloud forms. Under some conditions, however, cloud pockets can develop that contain large droplets of water or ice that fall into clear air as they evaporate. Such pockets may occur in turbulent air near a thunderstorm. Resulting mammatus clouds can appear especially dramatic if sunlit from the side. These mammatus clouds were photographed over Regina, Saskatchewan, Canada during the summer of 2012.

Learned about the Tetons in Mr. Fisher's elementary school geography class.
I attended a "real" school!
We studied "real" Science.
Never, however, "Paps of Jura." Thank you!

They’re real and they’re spectacular.

My pleasure. The shore of Avalon in the song is on Catalina island; the tourist boat to the island used to play that song during the trip (according to Groucho Marx).

Your illustrations of Mammatus clouds are good. Here are some additional ones.
