When stable air is forced to lift over a mountain range, it initially cools at the dry adiabatic lapse rate, which is 10°C per 1000 meters. However, as the air rises and cools, it eventually reaches its dew point and becomes saturated. At this point, the air cools at the moist adiabatic lapse rate, which is less than the dry adiabatic lapse rate. If the air continues to rise and cool, it will eventually cool to a temperature colder than the surrounding air, making it unstable and capable of rising on its own. Therefore, the air in this scenario is conditionally unstable.
