Which weather pattern is an indication of a stable atmosphere?

The presence of stratiform clouds is indeed indicative of a stable atmosphere. In meteorology, stability refers to the atmosphere's ability to resist vertical motion. A stable atmosphere tends to promote horizontal rather than vertical movements of air, and stratiform clouds, which form in stable conditions, exhibit a layered appearance. These clouds are often associated with steady precipitation and are typically found in overcast conditions.

In contrast, severe thunderstorms and high turbulence are signs of instability in the atmosphere, where rising air and strong updrafts can lead to chaotic weather patterns. Clear skies can suggest stability but do not guarantee it, as stable conditions could sometimes occur with a different cloud formation or during very dry air scenarios. Thus, the formation of stratiform clouds stands out as a clear indicator of a stable atmosphere, highlighting the balance between atmospheric pressure and temperature.
