Bergeron-Findeisen theory

Bergeron-Findeisen theory

[′berzh·ə‚rän ¦fin‚dīz·ən ‚thē·ə·rē]
(meteorology)
The theoretical explanation that precipitation particles form within a mixed cloud (composed of both ice crystals and liquid water drops) because the equilibrium vapor pressure of water vapor with respect to ice is less than that with respect to liquid water at the same temperature. Also known as ice-crystal theory; Wedener-Bergeron process.
