RAYLEIGH SCATTERING

Small, polarizable molecules scatter blues more and reds less. This is why the sky is blue.

This is also why bright or white objects redden/yellow with distance toward the horizon.

Another type of atmospheric perspective is Rayleigh scattering, and this happens with polarized molecules.

This is also why bright or white objects redden/yellow with distance toward the horizon.

There exists an electromagnetic charge within photons in light which means there's a potential for electromagnetic reactions. The atmosphere is made up of O2 (oxygen) or N2 (nitrogen) which are polarizable molecules.

Small, polarisable molecules scatter blues more and reds less. This is why the sky is blue. This is also why bright or white objects redden/yellow with distance toward the horizon.

With these certain types of polarisable molecules, there exists a complex interaction that relates to the probability filed of light.

White light tends to scatter the blues a lot and it tends to scatter the reds a lot less.

The whole sky is going to be blue because it is caused by the rayleigh scattering. This process also happens with the shadows (in the mountains), where we'll see more blue.

This is also why bright or white objects redden/yellow with distance toward the horizon.

So if the sun is in the sky,( it usually trends towards a white-yellow colour) and as it descends toward the horizon it will appear very red/orange. Any light that bounces off the clouds at that point becomes very red; this phenomenon is caused by Rayleigh scattering.

And an easy way to remember this is that blue wavelengths are very tight and red wavelengths are very long, so if those are high in energy and come into contact with any given object, there's a higher likelihood that the blues are going to interact with the object than the reds.

Will come across this occurrence in clouds also.

You can see these effects present with snow too. As shown above, looking at the snow covered mountains, you can see the yellow tint they take as they get distant.

ATMOSPHERIC Density and Composition Fluctuations

The atmosphere consists of large masses of warm and cool part levels that make it up rather than small discrete groups of atoms.

This process is called is "convection cells"

Mies Scattering

Most clouds are made of tiny ice and water particles that scatter white light.

Clouds take on their colour from a process called "Mies Scattering".

How does "Mies Scattering" occur?

The properties that make up water (usually very tiny particles that are about the same wavelength as light), float within the cloud and when light scatters throughout the atmosphere there is very little colour or light lost. Every time light scatters it loses some of its strength/brightness.

But as the water particles get larger they absorb more light, making the cloud darker.

Variations in droplet size sometimes occur on extremities.

Clouds are not made out of a single size particle, sometimes those particles tend to get bigger and as they get larger they lose some of the mies scattering. Mies scattering only happens with the smallest particles and because of that those larger particles tend to stay brighter.
