This research "shows that cirrus clouds
are forming on the same types of particles that people are producing" by such activities as industrial manufacturing, says Brian Toon of the University of Colorado at Boulder.
Lidar, on the other hand, calculates the precise height of cirrus clouds
and explores complex multilayered clouds of different sizes at various altitudes.
Unusually deep wintertime cirrus clouds
at altitudes exceeding 13.
To complement the ARM cloud radar simulator and provide a complete evaluation of model clouds, other ARM instrument simulators need to be developed, such as an ARM lidar simulator that would help identify model issues in simulating high thin cirrus clouds
and a laser ceilometer simulator for providing information on cloud-base height.
Clear skies coupled with high, thin and wispy cirrus clouds
, said Jeff Frame, teaching assistant professor of atmospheric sciences at the University of Illinois at Urbana-Champaign.
In his distinguished career, Demoz has led several major scientific projects, such as the International H2O Experiment (IHOP) in 2002, which collected measurements of water vapor and other particles in Earths atmosphere, and documented characteristics of cirrus clouds
, wispy high-altitude clouds whose role in climate is still poorly understood.
And there are problems with cloud seeding, too, which might be done to disperse cirrus clouds
, preventing them from trapping heat-the main problem is lack of precision; doing it wrong could lead to more warming, for example.
full) perspective in Science, researchers investigate the pros, cons and nuances of thinning cirrus clouds
to allow more heat to escape Earth.
On this morning, wispy cirrus clouds
draw long lines above the range.
Contrails, and the cirrus clouds
that evolve from them, have a larger impact on Earth's atmosphere than all the aviation-related carbon dioxide emissions since the first powered flight by the Wright brothers.
Despite its extreme thinness, the delicate crescent stands out boldly in a clear sky and actually is fairly easy to spot if the sky is free of haze or cirrus clouds
Unlike rainbows, where sunlight refracts through raindrops, circumzenithal arcs occur when sunlight refracts through ice crystals in cirrus clouds
Have students describe the appearance of cirrus clouds
, (thin, wispy, white) Write this description in the chart.
The jet stream is powering through at 220mph some 28,500 feet above us and it is pushing cirrus clouds
I want the blue kind with the cirrus clouds
streaking like ladders across it.
