Bacteria that colonize tiny plastic fragments drifting through the atmosphere can significantly enhance those particles’ ability to trigger ice crystal formation inside clouds, according to research ...

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 ...

When you have looked into western Montana's skies in the past, you may have noticed a fascinating object over the mountains. They commonly look like a stack of ...

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, ...

Marine bacteria carried by warm and moisture-laden atmospheric rivers contribute to the formation of ice clouds at unexpectedly high temperatures in high-latitude regions, research from Japan suggests ...

This experiment demonstrates how clouds form in our atmosphere through the interaction of warm and cold air. You'll create a miniature version of this natural process ...
