Ice Clouds Born
2017/11/24
Something almost magical happens when you put a tray full of sloshing, liquid water into a freezer and it comes out later as a rigid, solid crystal of ice. Chemists at the University of Utah have pull...
An integrated modeling study on the effects of mineral dust and sea salt particles on clouds and precipitation
