The clouds are fascinating whatever their form, it is still easy to lose time while watching from the ground. They always seem to be made of fanciful shapes and changing throughout the day.
But some weather events are more rare than others. Take these amazing clouds, for example.
These are mammatus clouds.

They look like small cotton balls suspended in the sky!
The name comes from the Latin word for "womb" or "worse".

So yes, they're boob clouds.
They give the sky, popcorn bubbly texture.

Bubbles, cotton balls and the breasts are all friendly, round things, but mammatus clouds are usually associated with severe thunderstorms and even tornadoes. They form the background of massive cumulonimbus.
There are several types of mammatus clouds.

They can look smooth, jagged, translucent or opaque. Everything depends on the weather
At present, there are several theories about how these clouds form.

Although they vary in mechanical details, most theories have to do with the meeting of warm and cold air. Different conditions produce different mammatus clouds, from dense clusters of individual bubbles bubble spaced on the open sky.
The conditions must be right for this kind of training.

generally aviators avoid flying if they see clouds because of their association with mammatus storms, but it seems that the plan had no choice but to defy them.
The clouds are dense and soft, or light and rare.

If ever see clouds like this, take a picture and admire the many strange shapes that nature can take - and then get inside, because it's probably going to rain.
