The Mysterious Nature of Clouds: Density, Temperature, and Structure

AI Thread Summary
The discussion explores the differences in cloud types, focusing on the high-altitude cirrus clouds, which are thin and ripple-shaped, versus the lower stratus and cumulus clouds, which are puffy and opaque. The composition of clouds plays a significant role, with cirrus clouds made of ice and lower clouds consisting of water droplets, affecting their density and visibility. Factors such as atmospheric density and temperature contribute to the formation and structure of clouds, preventing them from dissipating like gases. The irregular shapes of clouds are attributed to varying air densities and pockets of turbulence, which promote condensation. Overall, these elements combine to create the distinct appearances and behaviors of different cloud types.

What causes the high up cirrus clouds to be ripple shaped and thin, while the lower stratus or cumulo nimbus clouds to be puffy and opaque?

Presumably, it must have something to do with atmospheric density and temperature...although how exactly seems uncertain.

Also, what causes clouds to congregate into visible structures? Why don't they just dissipate/diffuse like a gas or smoke in another? What holds clouds together?

I think a major factor in this is that the higher clouds are composed of ice, while the lower down clouds, being warmer, are made up of water droplets...

So is it correct to say that since the density of ice is the lower than the density of water, the greater obscurity of low altitude clouds is a result of diffraction (due to smaller particle diameters) while at high altitudes it is the result of absorption?

How do you explain the irregular shapes of clouds? Why doesn't the atmosphere just look like muddy water (i.e. the clouds just disperse into a homogeneous, featureless, mass)?
 
High cirrus clouds are lower density as stated, but remember, they aren't a solid block of ice. They are MUCH lower density than clouds at low altitude for two reasons: One, the density of the atmosphere itself is many times (10x or so, probably) thinner at the altitude of cirrus clouds. And two, at lower temperature, the air holds far less water than at high temperature.

One thing I've noticed when travellingn in a small aircraft is that the atmosphere itself is not smooth. Pockets of verying air-density can actually be felt as one flies through them. This "bumpy air" is especially noticable at the edges of clouds. I don't know what other factors are involved, but this change in density itself would be enough to cause condensation to occurr.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
