8C, so it's likely ice crystals could have formed in high cirrus clouds
Normally we carefully avoided those towering cloud castles of violent turbulence, but that one was masked in some cirrus clouds
The AFCRL controlled U-2 aircraft investigated the radiation characteristics of high-altitude jet stream Cirrus clouds
While some contrails swiftly disappear, others form widespread cirrus clouds
which block both the sun's rays and heat energy from the ground.
Contrails--those white lines of vapor left by jets crisscrossing the sky--contribute to the formation of cirrus clouds
as the lines break up.
gain access to new data including ozone depletion and the size of water particles in cirrus clouds
Some have identified the lights as merely a circum-horizontal arc--an unusual, horizontal rainbow refracting through ice crystals in cirrus clouds
Because the air temperature there is below freezing, cirrus clouds
are made up of ice crystals instead of liquid water droplets.
They depict 15 different types of clouds, from the frightening cumulonimbus with a tornado whirling beneath to the choppy cirrus clouds
that often precede a storm.
According to the International Panel on Climate Change (IPCC), aerosol particles that are emitted in aviation such as soot, metals and sulfuric acid can indirectly influence climate change by causing additional cirrus clouds
to form, which in turn trap the heat rising from the Earth's surface.
If the Living Room tethers you to water and land, the Reading Room on the 10th floor unleashes a user for flights of imagination in an atmosphere evoking cirrus clouds
The formation of wispy cirrus clouds
is not a simple matter.
Alan Brown, a spokesman for the National Aeronautics and Space Administration, said the delay could improve the plane's chances of reaching 100,000 feet because high cirrus clouds
present Saturday may be gone today, permitting more sunlight to charge the aircraft's solar cells.
They suggest that the visibility of the constellation might be affected by the presence of wispy cirrus clouds
high in the atmosphere.
This artwork demonstrates the spectacular effects that a great watercolorist such as Palmer can achieve, from the cirrus clouds
and streaming sunlight to the soft canopy of leaves and shimmering swirls of water.
