Document Summary
Saturated adiabatic lapse rate if a saturated parcel containing water droplets were to sink, it would compress and warm at this lapse rate. 4-9degc/1000m: a warm, saturated air parcel, when forced to cool, condenses more liquid water than cold, saturated air does when it is forced to cool, the same amount (the added condensation liberates more latent heat. Lifting condensation level: the height at which saturation occurs. If the rising air is colder than it"s environment, it will be more dense and will sink back to its original level; we say the air is stable because it resists upward movement. What are inversions: an atmospheric condition where the air becomes warmer with elevation. Frontal inversions: forms along boundaries where cold air hits warm air. Inversions that form when air slowly sinks over a large area: associated with high pressure areas.
