Astronomy Picture of the Day - Mammatus Clouds over Saskatchewan

Explanation: When do cloud bottoms appear like bubbles? Normally, cloud bottoms are flat. This is because moist warm air that rises and cools will condense 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. The mammatus clouds pictured here, lasting only a few minutes, were photographed over Regina, Saskatchewan, Canada, just after a storm in 2012.

They are boob clouds.
The root word is mammatus, for resemblance to breasts.

No. They just look like butts hanging down from the sky. I didn’t name them that.

Okay. I get that. I like it better than what these billhillies call them.

Mammotus here in Kansas Usually accompanied by thunderstorms and tornados and television weathermen.

I have never seen "String of Peals" mammotus like these however. Maybe riding the Jet Stream?

They don’t look like tatas.

The look like long strings of gummy Krabby Patties...

I know I’m picking nits here but the study of clouds is Nephology.

Run-away....Run-away.

Gonna hit the fan quick.

What a pic, thanks for sharing.

Those bubbles represent a major downburst about to explode.
