Novel study uncovers the way coughs and sneezes stay airborne for long distances
The next time you feel a sneeze coming on, raise your elbow to cover up that multiphase turbulent buoyant cloud you're about to expel.
Potential solution to meteorite mystery: Chondrules may have formed from high-pressure collisions in early solar system
(Phys.org) —A normally staid University of Chicago scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. "I'm a fairly sober guy. People didn't ...
Insoluble dust particles can form cloud droplets affecting global and regional climates
New information on the role of insoluble dust particles in forming cloud droplets could improve the accuracy of regional climate models, especially in areas of the world that have significant amounts of mineral ...
Lasers could be used to make rain (w/ Video)
Venus Express spies rainbow-like 'glories'
(Phys.org) —A rainbow-like feature known as a 'glory' has been seen by ESA's Venus Express orbiter in the atmosphere of our nearest neighbour – the first time one has been fully imaged on another planet.
Takeoffs and landings cause more precipitation around major airports
Researchers have found that areas near commercial airports sometimes experience a small but measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions.
Researchers study relationship between temperature and atmospheric aerosol abundance
As temperatures warm, plants release gases that help form clouds and cool the atmosphere, according to research from IIASA and the University of Helsinki. The new study, published in Nature Geoscience, identi ...
The role of goop: Research shows pollution doesn't change the rate of droplet formation
When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn't matter that much. And that's good news for reducing the uncertainty of climate model predictions.
Danish experiment suggests unexpected magic by cosmic rays in cloud formation
According to the theory, small clusters of molecules in the atmosphere have difficulty growing large enough to act as "cloud condensation nuclei" on which water droplets can gather to make our familiar low-altitude ...
Organic vapors affect clouds leading to previously unidentified climate cooling
University of Manchester scientists, writing in the journal Nature Geoscience, have shown that natural emissions and manmade pollutants can both have an unexpected cooling effect on the world's climate by mak ...
Revealed: The Earth's 'electrical heartbeat' seen in clouds
(Phys.org) —The height of clouds changes by up to 200m during a day under the influence of a global 'electrical heartbeat' in the atmosphere, scientists at the University of Reading have discovered.
The brass ring of climate modeling
Finding a simple way to express complex climate processes is the ultimate prize. Scientists at Pacific Northwest National Laboratory, University of Leeds, Colorado State University, the National Aeronautics ...
CLOUD sees through the haze
The CLOUD (Cosmic Leaving OUtdoor Droplets) experiment at CERN, which is studying whether cosmic rays have a climatically significant effect on aerosols and clouds, is also tackling one of the most challenging ...
Experiment would test cloud geoengineering as way to slow warming
Even though it sounds like science fiction, researchers are taking a second look at a controversial idea that uses futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight ...
