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 ...

Tiny particles bubbling up from melting Arctic sea ice play a key role in cloud formation, suggests new research. The discovery may explain why Arctic clouds behave differently — and lead to improved ...

Tiny particles bubbling up from the tops of melting sea ice into the Arctic sky may be a key, understudied element of cloud formation in that climate-sensitive region. Ice-nucleating particles can ...

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 ...

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 ...

A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional climate processes far beyond the polar region. Over the last few decades, ...

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 ...

Penguin colonies across Antarctica are literally changing the weather—and it’s all about their droppings. New research reveals that ammonia from penguin guano creates massive hotspots of atmospheric ...
