| Bergeron process | a theory that relates the formation of precipitation to supercooled clouds |
| Advection fog | fog formed when warm mosit air is blown over a cool surface and chilled below the dew point |
| condensation nuclei | are small particles about which cloud droplets form |
| clouds | is a visible mass of droplets or frozen crystals floating in the atmosphere above the surface of the Earth |
| cumulus | is a type of cloud with noticeable vertical development and clearly defined edges |
| dew | is water in the form of droplets that appears on thin, exposed objects in the morning or evening |
| fog | is a cloud in contact with the ground |
| freezing nuclei | solid particles that have a crystal form resembling that of ice |
| frost | is the solid deposition of water vapor from saturated air |
| glaze | a layer of ice caused by freezing rain |
| hail | is a form of precipitation which consists of balls or irregular lumps of ice |
| rain | is a type of precipitation, a product of the condensation of atmospheric water vapor that is released on the Earth's surface |
| rime | is a coating of ice |
| sleet | A mixture of snow and rain |
| snow | is a type of precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds |
| steam fog | fog having the appearance of steam |
| stratus | is a cloud belonging to a class characterized by horizontal layering with a uniform base |
| super cooled | when water droplets stay liquid even below freezing |
| upslope fog | fog created when air moves up a slope and cools adiabatically |
| white frost | is a solid deposition of ice which forms directly from water vapor contained in air |
| cirrus | clouds are characterized by thin, wisplike strands, often accompanied by tufts, leading to their common name of 'mare's tail |
