The actual phenomenon that is sometimes called heat lightning is simply cloud-to-ground lightning that occurs very far away, with thunder that dissipates before it reaches the observer. [2] At night, it is possible to see the flashes of lightning from very far distances, up to 100 miles (160 km), but the sound does not carry that far. [3]
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]
The word comes to English via the French (se) mirer, from the Latin mirari, meaning "to look at, to wonder at". [ 2 ] Mirages can be categorized as "inferior" (meaning lower), "superior" (meaning higher) and " Fata Morgana ", one kind of superior mirage consisting of a series of unusually elaborate, vertically stacked images, which form one ...
This is because long-wavelength (red) light is scattered less than blue light. The red light reaches the observer's eye, whereas the blue light is scattered out of the line of sight. Other colours in the sky, such as glowing skies at dusk and dawn. These are from additional particulate matter in the sky that scatter different colors at ...
Everywhere, the planet showed signs of heat swoon last year, with record high levels of water vapor, methane, and carbon dioxide in the atmosphere; record low expanses of sea ice around Antarctica ...
That is, the light of each shell adds to the total amount. Thus the more shells, the more light; and with infinitely many shells, there would be a bright night sky. While dark clouds could obstruct the light, these clouds would heat up, until they were as hot as the stars, and then radiate the same amount of light.
A light pillar or ice pillar is an atmospheric optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source. The effect is created by the reflection of light from tiny ice crystals that are suspended in the atmosphere or that comprise high-altitude clouds (e.g. cirrostratus or cirrus clouds). [1]
Even with the heat on in my apartment and my windows closed, the Ice Cube maintained its cool temperature and helped prevent me from overheating in bed — even after sleeping with it for a few hours.
