What is a common result of lifting a stable air mass?

• A. Formation of cumulus clouds.
• B. Formation of stratiform clouds.
• C. Increased vertical activity.
• D. Clear skies.

Answer: (B)

Lifting a stable air mass typically leads to the formation of stratiform clouds. When stable air is lifted, it does not tend to rise rapidly or develop strong upward currents, resulting in a broad, layered cloud formation rather than vertical development. Stratiform clouds form when moist, stable air gradually rises, cools, and condenses into cloud layers across a wide area. This is often associated with slower, more widespread precipitation, rather than the localized thunderstorms or vertical clouds that would occur with unstable air. In contrast, cumulus clouds (associated with unstable air) and increased vertical activity (indicative of convection) are not expected outcomes from the lifting of stable air masses. Similarly, clear skies do not usually result from lifting stable air, as this action typically promotes cloud formation instead.
