This process of reflection/absorption is what causes the range of cloud color from white to black. [19] Other colors occur naturally in clouds. Bluish-grey is the result of light scattering within the cloud. In the visible spectrum, blue and green are at the short end of light's visible wavelengths, while red and yellow are at the long end.

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 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 .
Red is also created by oxygen but in the highest part of the atmosphere at more than 150 miles above the Earth's surface. Purple and blue are related to nitrogen, with purple lights appearing ...
Rayleigh scattering of sunlight by Earth's atmosphere causes the blue color of the sky, which tends to scatter blue light more than red light. Some daylight in the early morning and late afternoon (the golden hours ) has a lower ("warmer") color temperature due to increased scattering of shorter-wavelength sunlight by atmospheric particulates ...
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 ...
[1] [2] Purple light mainly occurs when the Sun is 2–6° below the horizon, from civil to nautical twilight, while the bright segment lasts until the end of the nautical twilight. [3] [4] Afterglow is often in cases of volcanic eruptions discussed, [5] while its purple light is discussed as a different particular volcanic purple light. [6]
