conditional instability"1. The state of a layer of unsaturated air when its lapse rate of temperature is less than the dry-adiabatic lapse rate but greater than the moist-adiabatic lapse rate.
Conditional instability - A type of atmospheric instability where the air is stable if it is dry, and unstable if it is saturated. Conduction - The transfer of sensible heat from a warm object to a cool object through contact.
Conditional Instability - The condition of moist air with an environmental lapse rate between the dry and wet adiabatic rates.
CONDITIONAL INSTABILITY Stable unsaturated air that will result in instability in the event or on the condition that the air becomes saturated. If the air is saturated, it is considered unstable; if air is unsaturated, it is considered stable.

Conditionally unstable air An atmospheric condition that exists when the environmental lapse rate is between the dry adiabatic rate and the moist adiabatic rate. Also called conditional instability.
(abbreviated LFC)—The level at which a parcel of air lifted dry-adiabatically until saturated and moist-adiabatically thereafter would become warmer than its surroundings in a conditionally unstable atmosphere. See conditional instability and ...
