Sometimes very ominous in appearance, mammatus clouds are harmless and do not mean that a tornado is about to form; a commonly held misconception. In fact, mammatus are usually seen after the worst of a thunderstorm has passed.

MAMMATUS clouds are most often associated with the anvil cloud & severe thunderstorms. They often extend from the base of a cumulonimbus but may also be found under altocumulus, altostratus, stratocumulus, & cirrus clouds as well as volcanic ash clouds^

For emphasis, I choose this picture. The bright purple on the black and white makes the trees stand out. The bright color makes the trees the focal point of the picture.

A fallstreak hole, also known as a punch hole cloud, is a large circular gap, that can appear in cirrocumulous or altocumulous clouds. are formed when the water temperature in the clouds is below freezing but the water has not frozen yet. When ice crystals do form it will set off a domino effect, due to the Bergeon process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud

This is a rare meteorological phenomenon called a ‘SKY PUNCH’. When people see these,they think it’s the end of the world. Ice crystals form above the high-altitude cirro-cumulo-stratus clouds,then fall downward, punching a hole in the cloudcover.
