Deposition
Conversion of a vapor directly to a solid
Humidity
Amount of water vapor in the air
Saturation
Dependent of the temperature of the air
Relative Humidity
Ratio of the air’s water vapor content to its capacity at that temperature
Dew point
temperature to which the air would have to be cooled to reach saturation
Adiabatic Changes
no heat added or subtracted
Frontal Wedging
cool air acts as a barrier over which warm air rises
convergence (convection)
as air converges it occupies a smaller space which requires the height of the column of air to increase
condensation nuclei
tiny bits of particulate matter serve as surfaces for water vapor condensation
Cirrus clouds

Cumulus clouds
globular individual cloud masses with a flat base and dome shape

Sheets or layers that cover most of the sky
advection
