Occurs when a rising air parcel becomes denser than the surrounding air. It will then return to its original position. When the density of the air parcel remains the same as the surrounding air after being lifted, it is also considered stable, since it does not have the tendency to rise or sink further.

Air that resists vertical development. Fair weather is dominant in stable air.
air with little or no tendency to rise, that is usually accompanied by clear dry weather.
Air that is colder than its surroundings and as such is resistant to upward movement.
Air in which temperature and moisture discourage formation of updrafts and downdrafts. Clouds will be low and flat Any precipitation will be steady.
Air that does not have a tendency to rise rapidly.
