When cirrus clouds are thick, they reflect only around 9 % of the incoming sunlight, but they prevent almost 50 % of the outgoing infrared radiation from escaping, thus raising the temperature of the atmosphere beneath the clouds by an average of 10 ° C ( 18 ° F )— a process known as the greenhouse effect.

Low, thick clouds ( such as stratocumulus ) primarily reflect incoming solar radiation, causing it to have a high albedo, whereas high, thin clouds ( such as Cirrus ) tend to transmit it to the surface but then trap outgoing infrared radiation, causing it to have low albedo.

Seen from below, clouds emit infrared radiation back to the surface, and so exert a warming effect ; seen from above, clouds reflect sunlight and emit infrared radiation to space, and so exert a cooling effect .< ref name = hartmann-1997 > Cloud representations vary among global climate models, and small changes in cloud cover have a large impact on the climate.

These clouds would then reflect the sunlight, creating a positive impact on climate mitigation.

Cirrocumulus clouds tend to reflect the red and yellow colours during a sunset and sunrise, and thus they have been referred to as " one of the most beautiful clouds ".

In Astronomy, reflection nebulae are clouds of interstellar dust which reflect the light of a nearby star or stars.

The radar also helps to estimate microphysical properties of clouds, such as particle size and mass content, which aids in understanding how clouds reflect, absorb and transform radiant energy passing though the atmosphere.

The high altitude clouds serve to reflect strongly-reddened sunlight still striking the stratosphere after sunset, down to the surface.

Land reflects anywhere from 10 – 25 % of the Sun's light, and clouds reflect around 50 %.

The clouds reflect sunlight, allowing the forest to regulate its temperature.

At times this may be moot due to weather, such as when the tall cumulonimbus clouds of a squall line of thunderstorms reflect the signal over the top, like an extremely tall radio tower.

During the day, since no clouds are present to reflect sunlight, there is more incoming shortwave solar radiation and temperatures rise.

More often than not, the troposphere will reflect the light, and leave out the sound-in these cases some fraction of the light emanating from distant thunderstorms ( whose distant clouds may be so low to the horizon as to be essentially invisible ) is scattered by the upper atmosphere and thus visible to remote observers.

During the day, since no clouds are present to reflect sunlight, there is more incoming shortwave solar radiation and temperatures rise.

Since clouds reflect sunlight, incoming shortwave solar radiation is less which causes lower temperatures during the day.

During the day, since no clouds are present to reflect sunlight, there is more incoming shortwave solar radiation and temperatures rise.

The clouds now reflect the image of the swirling leaves ; this is a parallelism that gives evidence that we lifted “ our attention from the finite world into the macrocosm ”.

He could even reflect clouds on the backdrop by painting different things on the mirrors that reflected light onto the dome.

Due to their high altitude and the curvature of the surface of the Earth, these clouds will receive sunlight from below the horizon and reflect it to the ground, shining brightly well before dawn or after dusk.

The major non-gas contributor to the Earth's greenhouse effect, clouds, also absorb and emit infrared radiation and thus have an effect on radiative properties of the atmosphere .< ref name =" kiehl197 ">

Analyzing the composition of interstellar clouds is achieved by studying electromagnetic radiation that we receive from them.

Some interstellar clouds are cold and tend to give out EM radiation of large wavelengths.

At least two fundamental non-terrestrial energy sources have been proposed: solar-powered energy generation ( unhampered by clouds ), either directly by solar cells or indirectly by focusing solar radiation on boilers which produce steam to drive generators ; and electrodynamic tethers which generate electricity from the powerful magnetic fields of some planets ( Jupiter has a very powerful magnetic field ).

The exception to the ionized gas distribution are HII regions which are bubbles of hot ionized gas created in molecular clouds by the intense radiation given off by young massive stars and as such they have approximately the same vertical distribution as the molecular gas.

Similar nebulae not illuminated by stars do not exhibit visible radiation, but may be detected as opaque clouds blocking light from luminous objects behind them ; they are called " dark nebulae ".

When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat.

Commercials aired several months in advance, ABC distributed half a million " viewer's guides ", which discussed the dangers of nuclear war and prepared the viewer for the graphic scenes of mushroom clouds and radiation burn victims.

Throughout the daytime, particularly when the skies are free of clouds, urban surfaces are warmed by the absorption of solar radiation.

The radiation that was received could originate from the planetary surface, clouds in the atmosphere, the atmosphere itself or a combination of these.

These satellites measure where infrared radiation is absorbed in the atmosphere, and if it is absorbed at cirrus altitudes, it is assumed that there are cirrus clouds in that location.

When they are thin and translucent, the clouds efficiently absorb outgoing infrared radiation while only marginally reflecting the incoming sunlight.

A prediction of this hypothesis is that the cirrus would move higher as the temperatures rose, increasing the volume of air underneath the clouds and the amount of infrared radiation reflected back down to earth.

A similar hypothesis put forth by Richard Lindzen is the iris hypothesis in which an increase in tropical sea surface temperatures results in less cirrus clouds and thus more infrared radiation emitted to space .< ref >

These include processes such as variations in solar radiation, variations in the Earth's orbit, mountain-building and continental drift, clouds and changes in greenhouse gas concentrations.

And then again perhaps the reason why he couldn't find time to do any of the things he had planned to do after retirement: reading, roaming, gardening, lying on his back and watching the clouds go by, was because he didn't want to do them.

The reflection of light back into space — largely by clouds — does not much affect the basic mechanism ; this light, effectively, is lost to the system.

Approximately 30 % is reflected back to space while the rest is absorbed by clouds, oceans and land masses.

The clouds can also remove from the atmosphere by converting it to nitric acid, which prevents the newly formed ClO from being converted back into.

The clouds are in an inverted arc, much like the official die, but the rays of the glory extend down beyond the clouds and in back of the eagle.

The station badge for the nearby RAF Waddington depicts Lincoln Cathedral rising through the clouds, a sight which returning bomber crews used to help find their way back to Waddington's airfield.

Carpo ( Καρπώ ), Carpho or Xarpo was the one who brings food-though Robert Graves in The Greek Myths ( 1955 ) translates this name as " withering ") was in charge of autumn, ripening, and harvesting, as well as guarding the way to Mount Olympus and letting back the clouds surrounding the mountain if one of the gods left.

They hurled the rib-boomerang and tore a huge hole in the clouds which startled Bobbi-Bobbi so much that he failed to catch the boomerang which fell back to Earth and killed the foolish men.

When news reached him that king Rusas I of Urartu was moving against him, he turned back to Lake Urmia in forced marches and defeated a Urartian army in a steep valley of the Uaush ( probably the Sahend, east of Lake Urmia, or further to the south, in Mannaea country ), a steep mountain that reached the clouds and whose flanks were covered by snow.

However, several top Democratic lawmakers in the House signed a letter on June 26, 2009, alleging that CIA Director Leon Panetta had asserted that the CIA misled Congress for a " number of years " spanning back to 2001, casting more clouds on the controversy.

As these clouds appeared their darkest, however, two events in the fall of 1977 helped reverse the trend and started the league back on the path to the great health it enjoys today.

Whereas most forms of skywave propagation use the normal and cyclic ionization properties of the ionosphere's F region to refract ( or " bend ") radio signals back toward the Earth's surface, sporadic E propagation bounces signals off smaller " clouds " of unusually ionized atmospheric gas in the lower E region ( located at altitudes of approx.

However, Wang Chong supports his theory by quoting a similar one of Gongyang Gao's, the latter's commentary on the Spring and Autumn Annals, the Gongyang Zhuan, compiled in the 2nd century BC, showing that the Chinese conception of rain evaporating and rising to form clouds goes back much farther than Wang Chong.

Plunged in this fire were demons and souls in human form, like transparent burning embers, all blackened or burnished bronze, floating about in the conflagration, now raised into the air by the flames that issued from within themselves together with great clouds of smoke, now falling back on every side like sparks in a huge fire, without weight or equilibrium, and amid shrieks and groans of pain and despair, which horrified us and made us tremble with fear.

( Alternatively, the Goddess forced the fairy back to her former duty of weaving colorful clouds, a task she neglected while living on earth with a mortal.

A wind vortex forms as the trade-winds pass around the north-west corner of Haleakala ( over Pukalani ) and blow southward down the central valley of Maui over Maalaea Bay and then circle back up-slope over Kihei bringing a " lei of clouds " late most mornings over Kula.

The smaller droplets make clouds more reflective, so that more incoming sunlight is reflected back into space and less reaches the Earth's surface.

The back of the P ' eng measures I don't know how many thousand li across and, when he rises up and flies off, his wings are like clouds all over the sky.

There is also a bird there, named P ' eng, with a back like Mount T ' ai and wings like clouds filling the sky.

Large tornadoes tend to come from larger, lower wall clouds closer to the back of the rain curtain ( providing less visual warning time to those in the path of an organized storm ).
