Good day, everyone


SolanaBogon, what you are describing here are Cumulonimbus Clouds which produce storms such as thunderstorms and so forth. Yes, they do have a flat bottom by nature.

Cumulus clouds, however, can develop in a much wider variety of atmosheric conditions than the Cumulonimbus. In fact, Cumulus is actually a category of a clouds with more variation than some people are aware. They can develop at different altitudes than other types of clouds and with more variety. Cumulus clouds can also develop in many parts of the world in any season, though summer is most common. A cumulus cloud can be small, gentle, and round like a cotton ball. It can also have a flat bottom, though not always. Some of them are large, too, which shows the variations in this category of clouds.

Sorry, for the error, but where I live, cumulus are big clouds who progress in altitude, and not little cotton ball, but, as you said, there is some types of cumulus.

I dont want to argue with you but.....

1-You can call them(in the pictures) cumulus if you want, but nevertheless they are AC,TCU or CB ( I could tell that a Spruce is an Oak... Both are trees, but I would be wrong :wink: )

2- Everywhere in the world that can have Towering cumulus and Cumulonimbus, you'll find that there is some cumulus around (little cotton ball), because they were as little as them, but took some expension because of the heat.


To answer the question about flat bottom of cumulus....
There can be both one(flat and not flat)
And the more big is the cloud, the more turbulant the air near would be

Have a nice day :mrgreen:
