  2. Atmospheric refraction - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_refraction

    Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1]

  3. Fog - Wikipedia

    en.wikipedia.org/wiki/Fog

    Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions.

  4. Crepuscular rays - Wikipedia

    en.wikipedia.org/wiki/Crepuscular_rays

    Particles in the air scatter short-wavelength light (blue and green) through Rayleigh scattering much more strongly than longer-wavelength yellow and red light. Loosely, the term crepuscular rays is sometimes extended to the general phenomenon of rays of sunlight that appear to converge at a point in the sky, irrespective of time of day. [3] [4]

  5. Cloud physics - Wikipedia

    en.wikipedia.org/wiki/Cloud_physics

    At small radii, the amount of supersaturation needed for condensation to occur is so large, that it does not happen naturally. Raoult's law describes how the vapor pressure is dependent on the amount of solute in a solution. At high concentrations, when the cloud droplets are small, the supersaturation required is smaller than without the ...

  6. Inversion (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Inversion_(meteorology)

    With sufficient humidity in the cooler layer, fog is typically present below the inversion cap. An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky.

  7. Cloud - Wikipedia

    en.wikipedia.org/wiki/Cloud

    Cloud droplets tend to scatter light efficiently, so that the intensity of the solar radiation decreases with depth into the gases. As a result, the cloud base can vary from a very light to very-dark-gray depending on the cloud's thickness and how much light is being reflected or transmitted back to the observer. High thin tropospheric clouds ...

    Get your telescope ready in September, when Saturn will take center stage in the sky and shine brighter than at any other point in the year. The planet will reach opposition on Sept. 21, around ...

  9. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    A simple example of this is being able to see farther in heavy rain than in heavy fog. 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.
