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.

Some clever (I’m guessing male) astronomer made up that name, I’m sure.

As I understand it, those can develop into tornadoes too, right?

“.... male astronomer made up that name..”
LOL! If it had been me.. I would call them string of pearls.

Is this weather picture a result of NASA being directed to put climate change on its agenda. I fail to see the connection with astronomy.

I’ve understood that mammatus clouds may indicate conditions that can be favorable for tornadoes, but I don’t think tornadoes actually form from mammatus clouds themselves.

Apparently the APoD people have run out of astronomical objects to feature. :’)

Probably he lived near the Grand Tetons, or maybe in Scotland near the Paps of Jura.
