Pure water freezes only at around -38°C (-36°F). Tiny mineral dust particles act as so-called ice nucleators—crystallization ...

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 ...

Salt and sugar from the sea can rise as far as the free troposphere, thereby influencing both cloud formation and the Arctic ...

Watch a rare cloud formation develop in real time without filters or visual effects. This footage captures the unusual structure and natural movement of the clouds as they form.

Rising temperatures are thought to reduce the number of ice crystals in clouds, leading to the formation of liquid-dominated clouds. However, a new study has found that Arctic warming is causing an ...

Graduate students analyze cloud formation data with research scientist Jesse Anderson, using the Pi Cloud Chamber to study atmospheric processes. × Michigan Tech's Pi Cloud Chamber is giving ...

Penguins’ poop may be making Antarctica cloudier — and helping mitigate the regional impacts of climate change. Gases emitted from the birds’ guano are supplying key chemical ingredients to form the ...

Scientists have observed that ammonia in penguin guano is directly related to cloud formation in Antarctica. Gaseous ammonia reacts with gaseous sulfur compounds in the Antarctic atmosphere to form ...

If your head's in the clouds this Monday, you're not alone. Meteorologist Ray Petelin and his daughter Elizabeth answer one of your questions about a unique cloud formation in this week's Hey Ray.
