Ice particles have systematic covariations and temperature dependences that are surprisingly consistent with a simple ice growth theory as revealed by satellites.
Cloud physics and chemistry
Researchers Quantify a Seeded Snowpack
In Idaho, three hour-long cloud-seeding events created the snow equivalent of about 282 Olympic-sized swimming pools’ worth of water.
Microphysics and Positive Lightning in Hokuriku Winter Clouds
The microphysics of the frequent, and frequently positive, lightning of Hokuriku winter clouds was investigated by systematic, in situ observation of individual precipitation particle type and charge.
New Observations of Thunderstorm Updrafts and Downdrafts
Unique measurements of air motion within deep convective clouds offer new insights in our understanding of these storms and provide constraints for weather and climate prediction.
Science Explains “Rough and Chaotic” Cloud Feature
Research on the newest entry in the International Cloud Atlas produces insights into what these cloud features are made of and how they form.
Designing Mountaintop Cloud Experiments
Whiteface Mountain Cloud Chemistry Workshop; Wilmington, New York, 16–17 September 2016
Understanding Causes and Effects of Rapid Warming in the Arctic
A new German research consortium is investigating why near-surface air temperatures in the Arctic are rising more quickly than in the rest of the world.
Icy Clouds May Counter Climate Warming Less Than Expected
A new analysis of cloud composition and behavior suggests that scientists have overestimated the ability of a type of mixed-phase ice-and-water cloud to mitigate climate change effects.
