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 ...

Clouds need two essential ingredients to form, and both must be present simultaneously for the process to begin. There are two ingredients needed for clouds to form: water and nuclei. The first ...

Snow can fall even when it's above 32 degrees at the surface, due to the colder temperatures where it forms in the clouds.

You wouldn't think that clouds and snow floating around in the sky get help from bacteria near the ground, but those tiny organisms can lend a helping hand in getting clouds to form. First off, let’s ...

The effects of industrial pollution on cloud formation have long interested scientists. Velle Toll, a climate physicist at the University of Tartu, uses satellite data to study how microscopic solid ...

Clouds form when water vapor—an invisible gas in the atmosphere—sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, we ...

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 ...
