Unstable air is characterized by its tendency to rise, which can be caused by heating (as warm air tends to rise) or by other mechanisms that encourage vertical movement, such as orographic lifting. Heating of air at the surface decreases its density, causing it to rise. Rising air expands and cools, leading to cloud formation and potentially precipitation if the air is moist, indicating instability.
