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 ...

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 ...

Molecular clouds constitute the principal reservoirs of cold, dense gas in the Milky Way, with masses ranging from tens to millions of solar masses. Predominantly composed of molecular hydrogen, they ...

Joint press release issued by the Alfred Wegener Institute, Leibniz Institute for Tropospheric Research and Max Planck Institute for Chemistry Antarctica plays a crucial role in the Earth’s climate ...

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 ...

Astronomers have captured the first direct evidence of a daily weather cycle on a planet outside our solar system, detecting ...
