Question

Quizplus · Accepted Answer

Falling snowflakes can survive in air with temperatures much above freezing if the air is unsaturated (i.e., not holding the maximum amount of moisture it can) and the wet-bulb temperature is at or below freezing. This is because the snowflake will evaporate some of the moisture in the surrounding air, causing cooling and re-freezing, which can help it survive even in relatively warm air. However, if the air is saturated (holding the maximum amount of moisture possible) and the wet-bulb temperature is above freezing, the snowflake will not be able to survive as it will immediately melt.
