Purple sky on the La Silla Observatory. [16] The sky can turn a multitude of colors such as red, orange, pink and yellow (especially near sunset or sunrise) and black at night. Scattering effects also partially polarize light from the sky, most pronounced at an angle 90° from the Sun.
Iridescent mid altitude clouds Iridescent polar stratospheric cloud at sunset over Aberdeen, Scotland Cloud iridescence, seen above the clouds covered with grey clouds, Pondicherry, India. Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon.
Purple skies aren't exclusive to hurricane-hit areas, but storms can contribute to creating the conditions needed to create the dazzling hue. "You don't necessarily have to have a tropical cyclone ...
Scattering and absorption are major causes of the attenuation of sunlight radiation by the atmosphere. During broad daylight, the sky is blue due to Rayleigh scattering, while around sunrise or sunset, and especially during twilight, absorption of irradiation by ozone helps maintain blue color in the evening sky. At sunrise or sunset ...
The Rayleigh sky causes a clearly defined polarization pattern under many different circumstances. The degree of polarization however, does not always remain consistent and may in fact decrease in different situations. The Rayleigh sky may undergo depolarization due to nearby objects such as clouds and large reflecting surfaces such as the ocean.
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.
In the case of alpenglow, which is similar to the Belt of Venus, [7] afterglow is used in general for the golden-red glowing light from the sunset and sunrise reflected in the sky, and in particularly for its last stage, when the purple light is reflected. [2] [1] The opposite of an afterglow is a foreglow, which occurs before sunrise ...
The sky formations are known as "cavum clouds" or "fallstreak holes." Here we explore unique facts about these "hole-punch clouds." Learn how passing airplanes shape their formation.
