A groundbreaking study on the freezing of water droplets suspended in air sheds light on a key process in Earth's water cycle: the transformation of supercooled water into ice. A groundbreaking ...

A deep layer of warm air, though, can completely melt the snowflake and leave behind no trace of ice crystals. The resulting raindrop is pure water. As it falls into the freezing air near the ...

the less heat energy the water requires to vaporize, or turn into steam. However, ice at sea level can form if the air temperature is above the freezing point, thanks to radiative cooling.
