Pores in atmospheric particles allow water to condense, leading to the formation of ice crystals in humid but unsaturated air. This is a new way of thinking of ice crystal formation in clouds, particularly cirrus clouds.

High in the atmosphere, ice crystals are born in thin, wispy cirrus. Most of this ice birthing, what researchers call ice nucleation, is initiated on particles of soot, dust, compounds, or other droplets. Researchers at Pacific ...
