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. [20] The short rays are more easily scattered by water droplets, and the long rays are more likely to be ...
Noctilucent clouds form mostly near the polar regions, [8] because the mesosphere is coldest there. [15] Clouds in the southern hemisphere are about 1 km (3,300 ft) higher than those in the northern hemisphere. [8] Ultraviolet radiation from the Sun breaks water molecules apart, reducing the amount of water available to form noctilucent clouds.
Low, ragged clouds that appear beneath the main cloud base. Formed from moist air lifted by outflow winds from a storm. Often mistaken for tornadoes, but they are typically harmless, indicating ...
Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates. One common example is the rainbow , when light from the Sun is reflected and refracted by water droplets.
The Met Office said lenticular clouds combined with the sunrise to create the stunning effect. The clouds tend to form "when air blows across a mountain range in certain circumstances" and when ...
Even if it is partly cloudy the eclipse can still be spectacular as seen in this 2017 photo.
Polar stratospheric clouds over Western Norway. The stratosphere is very dry; unlike the troposphere, it rarely allows clouds to form.In the extreme cold of the polar winter, however, stratospheric clouds of different types may form, which are classified according to their physical state (super-cooled liquid or ice) and chemical composition.
A funnel cloud is usually visible as a cone-shaped or needle like protuberance from the main cloud base. Funnel clouds form most frequently in association with supercell thunderstorms, and are often, but not always, a visual precursor to tornadoes. Funnel clouds are visual phenomena, but these are not the vortex of wind itself. [2]
