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.

Earthquake lights may be classified into two different groups based on their time of appearance: (1) preseismic earthquake light, which generally occur a few seconds to up to a few weeks prior to an earthquake, and are generally observed closer to the epicenter and (2) coseismic earthquake light, which can occur either near the epicenter ...
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 ...
In practice, color temperature is most meaningful for light sources that correspond somewhat closely to the color of some black body, i.e., light in a range going from red to orange to yellow to white to bluish white. Although the concept of correlated color temperature extends the definition to any visible light, the color temperature of a ...
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.
People have reported purple skies in the aftermath of several different hurricanes -- from the Category 1 Hurricane Florence, a large, slow-moving hurricane during 2018, to Hurricane Michael, the ...
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.
Steve is visually different from auroras, which are caused by electrically charged particles that glow when they interact with the atmosphere and appear as dancing ribbons of green, blue or red.
