The temperature at which the air is saturated The ratio of the air's water vapor content relative to its water vapor capacity 5. The parcels reach colder air Expansion of gases causes cooling Compression of gases causes cooling Water vapor condenses 8. The ratio of the amount of air compared to the amount that could be held if the air were saturated The ratio of the weight of water vapor to the weight of the air without water vapor 9. No water vapor is left in the air. Air is forced to rise and is warmed by the adiabatic process.
Condensation has a drying effect on the air.
As air descends, adiabatic warming causes clouds to evaporate. Convection Advection Orographic lifting Frontal lifting 11. When cold air is in contact with the ground. During the passage of a cold air mass. When air masses of contrasting temperatures and moistures meet.
