We also see the Rayleigh effect at play in: -Sunsets where the sky is red.Light has to pass through a larger part of the atmosphere when the sun is lower on the horizon. Red, orange and yellow ...
Rayleigh scattering of sunlight in Earth's atmosphere causes diffuse sky radiation, which is the reason for the blue color of the daytime and twilight sky, as well as the yellowish to reddish hue of the low Sun. Sunlight is also subject to Raman scattering, which changes the rotational state of the molecules and gives rise to polarization ...
The red light reaches the observer's eye, whereas the blue light is scattered out of the line of sight. Other colours in the sky, such as glowing skies at dusk and dawn. These are from additional particulate matter in the sky that scatter different colors at different angles. Halos, afterglows, coronas, polar stratospheric clouds, and sun dogs.
The Rayleigh sky model describes the observed polarization pattern of the daytime sky. Within the atmosphere, Rayleigh scattering of light by air molecules, water, dust, and aerosols causes the sky's light to have a defined polarization pattern. The same elastic scattering processes cause the sky to be blue.
The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth 's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere .
Ascent (negative values; blue to violet) is concentrated close to the solar equator; descent (positive values; red to yellow) is more diffuse but also occurs mainly in the Hadley cell. The wind belts girdling the planet are organised into three cells in each hemisphere—the Hadley cell, the Ferrel cell, and the polar cell. Those cells exist in ...

The skies over St. Petersburg, Florida, turned purple as Hurricane Milton approached the Florida coast last week, a phenomenon that has been seen in other hurricanes such as Delta, Dorian, and ...
