 | | Precipitation forms within clouds through two main processes: the collision-coalescence process and the Bergeron process. |
| | Precipitation types such as ice pellets, snow pellets, and freezing rain result mainly from temperature variations in the air through which rain or snow fall. |
| | Most efforts at precipitation modification are founded on the theory that some clouds are deficient in freezing nuclei. |
