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 ...

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 ...

A new study found tiny microplastics — sized between 7.1 to 94.6 micrometers — in cloud water collected from high-altitude summits in Japan. The researchers suggest that microplastics could therefore ...
