Cloud formation—how feldspar acts as ice nucleus

In the atmosphere, feldspar particles act as ice nuclei that make ice crystals grow in clouds and enable precipitation. The discovery was made by researchers of Karlsruhe Institute of Technology (KIT) and University College ...

How supercooled water is prevented from turning into ice

Water behaves in mysterious ways. Especially below zero, where it is dubbed supercooled water, before it turns into ice. Physicists have recently observed the spontaneous first steps of the ice formation process, as tiny ...

Why it snows so much in the frozen North

(Phys.org) —When it doesn't show signs of stopping, most of us just mumble a few choice words and get out the snow shovel. Scientists, however, wonder where all that snow is coming from, particularly in pristine places ...

The role of bacteria in weather events

Researchers have discovered a high concentration of bacteria in the center of hailstones, suggesting that airborne microorganisms may be responsible for that and other weather events. They report their findings today at ...

Clouds + Mineral Dust = Rain

A team of atmospheric scientists, including Dr. Xiaohong Liu of Pacific Northwest National Laboratory (PNNL), found a critical link between the size of dust particles in clouds and their likelihood to produce rain.
