  2. Mandevilla sanderi - Wikipedia

    en.wikipedia.org/wiki/Mandevilla_sanderi

    Emerging flower. Mandevilla sanderi is a shrub with a naturally bushy habit, 2–3 meters high, or 4.5 meters (15 feet) if the climate is warm. It is able to develop long, woody stems based on lignin and climbs by twining around some support.

  3. 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 .

  4. Rayleigh sky model - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_sky_model

    The red band represents the circle in the north-zenith-south plane where the sky is highly polarized. The cardinal directions (N, E, S, W) are shown at 12-o'clock, 9 o'clock, 6 o'clock, and 3 o'clock (counter-clockwise around the celestial sphere , since the observer is looking up at the sky).

  5. 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]

  6. Sun dog - Wikipedia

    en.wikipedia.org/wiki/Sun_dog

    Two sun dogs often flank the Sun within a 22° halo. The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun ...

  8. Rayleigh scattering - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_scattering

    Rayleigh scattering causes the blue color of the daytime sky and the reddening of the Sun at sunset. Rayleigh scattering (/ ˈ r eɪ l i / RAY-lee) is the scattering or deflection of light, or other electromagnetic radiation, by particles with a size much smaller than the wavelength of the radiation.

  9. Sprite (lightning) - Wikipedia

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

    A sprite over Southeast Asia as seen from space.. Sprites or red sprites are large-scale electric discharges that occur in the mesosphere, high above thunderstorm clouds, or cumulonimbus, giving rise to a varied range of visual shapes flickering in the night sky.
