2 unusual facts about Bergeron process


Bergeron process

The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron and W. Findeisen), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the saturation vapor pressure over ice.

Ice crystals can form from heterogeneous deposition, contact, immersion, or freezing after condensation.
