  2. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    The exact cause of green thunderstorms is still unknown, but it could be due to the combination of reddened sunlight passing through very optically thick clouds. Yellowish clouds may occur in the late spring through early fall months during forest fire season. The yellow color is due to the presence of pollutants in the smoke.

  3. 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 ...

  4. Ocean color - Wikipedia

    en.wikipedia.org/wiki/Ocean_color

    Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean, while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [1]

  5. 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 ...

  6. Cloud iridescence - Wikipedia

    en.wikipedia.org/wiki/Cloud_iridescence

    The colors resemble those seen in soap bubbles and oil on a water surface. It is a type of photometeor. This fairly common phenomenon is most often observed in altocumulus, [1] cirrocumulus, lenticular, [2] and cirrus clouds. [3] [4] [5] They sometimes appear as bands parallel to the edge of the clouds.

  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 .

  9. Milky seas effect - Wikipedia

    en.wikipedia.org/wiki/Milky_seas_effect

    Milky sea effect off the coast of Somalia in the Indian Ocean. Milky seas (Somali: Kaluunka iftiima; English: Milky seas), sometimes confused with mareel, are a luminous phenomenon in the ocean in which large areas of seawater (up to 100,000 km 2 or 39,000 sq mi [1]) appear to glow diffusely and continuously (in varying shades of blue).
