Specular scattering in cirrus clouds
SPIE Proceedings, 1995The radiative properties of cirrus clouds are of wide interest because of the visually striking effects they produce, the significant global coverage of cirrus and thin cirrus, and their intrinsic complexity. Within a limited class of crystal shape and size, hydrodynamic forces tend to orient the crystals with their long axis nearly horizontal, which ...

Light and Color in the Open Air, 1997
On 20 January 1995, an apparent cirrus cloud glory was photographed over central Utah from an airline passing through the 10.7 km MSL level as it began its descent into Salt Lake City International Airport. The cirrus cloud layer was geographically widespread and optically thin enough to view the snow-covered Wasatch Mountain Plateau beneath the cloud.

Volcanic impact on cirrus clouds
2020<p>Cirrus clouds have a net warming effect on climate due to their high altitude and low optical thickness. Small changes in their properties may however shift this to a stronger warming or a cooling. Aerosol particles can strongly affect cirrus cloud properties since they can act as ice nuclei (IN) for the ice crystals.

Can cirrus clouds produce glories?
Applied Optics, 1998A vague glory display was photographed over central Utah from an airplane beginning its descent through a cirrus cloud layer with an estimated cloud top temperature of -45 and -55 degrees C. Photographic analysis reveals a single reddish-brown ring of 2.5-3.0 degrees radius around the antisolar point, although a second ring appeared visually to have ...

Investigating contrails within cirrus clouds
2020<p>Effects of aviation on the Earth&#8217;s radiation budget and climate related to CO<sub>2</sub> emissions and from the formation of linear contrails and contrail cirrus have been the focus of detailed studies. Aviation effects on existing cirrus clouds are much less investigated.

Journal of the Atmospheric Sciences, 1971
Abstract Cirrus clouds may act to cool or warm the earth's surface, depending upon their infrared emissivity. Direct observation of cirrus cloud emissivities in mid-latitude and tropical environments indicates that cirrus may produce different effects at different latitudes.

Climatic Effects of Cirrus Clouds
1979Publisher Summary This chapter reports the investigations of the radiative balance of the Earth-atmosphere systems, its sensitivity to cloud and aerosol scattering, and the impact, which an increase in cirrus cloudiness might have upon that balance.
