DARWIN, Australia, Feb. 27, 2014 /PRNewswire-USNewswire/ -- NASA researchers are part of an international team working to improve aviation safety by studying high altitude ice crystals during a flight campaign now under way in Darwin, Australia. http://photos.prnewswire.com/prnvar/20081007/38461LOGO NASA and its North American partners are supporting the European Airbus-led High Altitude Ice Crystals (HAIC)/High Ice Water Content (HIWC) field campaign in the "land down under" through...

Meteor Smoke Helps Form Noctilucent Clouds

Watch the Video : [ Meteor Smoke Makes Strange Clouds ] Lee Rannals for redOrbit.com - Your Universe Online Bits of "meteor smoke" have been detected in a noctilucent cloud (NLC), supporting an already existing theory. Noctilucent clouds were first noticed in 1885 about two years after the eruption of Krakatoa. Ash from the volcano caused great sunsets, making it a global past time for people to sit and look up at the sky at dust. A German named T.W. Backhouse, who is credited...

Author: Dr. Tony Phillips - Science @ NASA NASA's Solar Dynamics Observatory (SDO), best known for cutting-edge images of the sun, has made a discovery right here on Earth. "It's a new form of ice halo," says atmospheric optics expert Les Cowley of England. "We saw it for the first time at the launch of SDO--and it is teaching us new things about how shock waves interact with clouds." Ice halos are rings and arcs of light that appear in the sky when sunlight shines through ice crystals in...

U.S. researchers say a new study of nascent clouds has revealed that a number of microorganisms"”including bacteria, spores and plants"”may play a role in cloud formation and weather patterns.Computer models have typically been the tool of choice for climatologists attempting to predict emerging weather patterns, partly due to the fact that it is extremely difficult to capture and measure ice crystals as they are forming in young clouds.The new study, published in the journal...

Atmospheric lead causes clouds to form more easily, could change pattern of rain and snow By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest that lead generated by human activities causes clouds to form at warmer temperatures and with less water. This could alter the pattern of both rain and snow in a warmer world.The lead-laden clouds come...

New technology to help with climate change predictions Scientists have created an instrument designed to help determine the shapes and sizes of tiny ice crystals typical of those found in high-altitude clouds, down to the micron level (comparable to the tiniest cells in the human body), according to a new study in Optics Letters, a journal published by the Optical Society. The data produced using this instrument likely will help improve computer models used to predict climate change. Among...

NASA -- Winter is here, snow is falling in many areas of the country, and some of us are already wishing for the return of hot summer days. But, would you believe that even on the hottest summer day the temperature inside some clouds remains icy and winter-like, producing temperature readings as cold as negative 70 degrees Celsius (negative 94 degrees Fahrenheit)? Would you also believe that the ice crystals that form at the top of big summertime clouds may help scientists predict next...

A Stratus cloud is a cloud belonging to a class distinguished by horizontal layering with a uniform base. This type of cloud is different from other clouds that are usually taller than they are wide (these are known as cumulus clouds). The term "˜stratus', In Latin, means layer or blanket. Stratus clouds are flat, featureless clouds of low altitude that can vary in color from dark gray to nearly white. A typical cloudy day usually features a sky filled with stratus clouds obscuring the view...

Cirrus clouds are thin wisplike strands, sometimes accompanied by patches. Their shape and arrangement lead to their common name of "mare's tail". These clouds can be so extensive that they are virtually identical to one another and hard to tell apart. Sometimes high altitude convection produces another form of cirrus called cirrocumulus. Many cirrus clouds produce hair-like filaments made of heavy ice crystals that precipitate from them. This precipitation often indicates the difference in...
