Answer: Clouds form when sufficiently moist air is cooled to the dew point temperature of the air or below, so that either liquid water droplets form on cloud condensation nuclei, or in the case of ...

FARGO — Cirrus clouds are the clouds with feathery tails. They are very high clouds, usually 20,000 to 30,000 feet above the ground, where the temperature is well below freezing. Even in summer, these ...

Some parts of the U.S. see well over 100 inches (2.5 meters) of snow per year. Edoardo Frola/Moment Open via Getty Images The thought of snow can conjure up images of powdery slopes, days out of ...

There are two ways snow can begin to form in clouds. When the air is very cold, water vapor can convert directly to ice through a process called “homogenous nucleation.” At temperatures between minus ...

Universally known to indicate that the winter season has arrived and known in the Inland Northwest to indicate that it is time to don warm boots and gloves to scrape your car before work, snow is ...

This rain and snow-inducing technique, called cloud-seeding, has been around for more than 60 years. The process involves “seeding” existing clouds with a harmless substance called silver-iodide to ...

A peculiarly large hole appeared in the clouds near Russia’s Norilsk Nickel factory, one of the world’s largest producers of nickel and a heavy air polluter. Scientist Velle Toll was intrigued by the ...

When you hear “man-made snow,” you might imagine a snow gun at a ski hill making fresh powder. While it isn’t quite the same as firing up a snow machine, when the conditions are right, snow that falls ...

As surface air temperatures rise above 0°C, snow and ice cover melts, resulting in the appearance of snow/ice-free barren and vegetated areas. These newly exposed surfaces release increased amounts of ...

Late-fall into winter is when the lake-effect snow machine kicks into gear again — and it's not just around the Great Lakes. Let's dive into the science behind lake-effect snow, how it creates such ...
