  2. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    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.

    en.wikipedia.org/wiki/Sprite_(lightning)

    Column sprite (C-sprite) – large-scale electrical discharges above the earth that are still not totally understood. Carrot sprite – a column sprite with long tendrils. Sprites are colored reddish-orange [ 5 ] in their upper regions, with bluish hanging tendrils below, and can be preceded by a reddish halo.

  4. Atmospheric circulation - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_circulation

    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 ...

    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 ...

  6. Rayleigh scattering - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_scattering

    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 ...

  7. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    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 ...

  8. Diffuse sky radiation - Wikipedia

    en.wikipedia.org/wiki/Diffuse_sky_radiation

    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 .

    A yellow weather warning for heavy rain has been issued for nearly all of Scotland on Hogmanay. Forecasters warned the deluge of rain could bring "significant disruption" in the build up to Hogmanay .
