What are characteristics of stable air mass?
Air mass having a stable stratification in its lower layer, and consequently free from convection, having a low degree of turbulence, and containing either stratiform clouds, fog, or no clouds at all.

What are the characteristics of stable and unstable air?
Atmospheric stability is defined as the resistance of the atmosphere to vertical motion. A stable atmosphere resists an upward or downward movement. An unstable atmosphere allows an upward or downward disturbance to grow into a vertical (convective) current.

What is a characteristic of a stable air?
Characteristics of stable air are cloud cover, smooth air, uninterrupted precipitation, and low visibility. Cloud cover describes stratiform clouds or fog which moves in a sheet and stay close to the ground so the air does not disturb the atmosphere.

What is stable air quizlet?
stable air – happens when warm air stays above cold air. The weather is likely to remain calm. unstable air – happens when there is a quick change in temperature. Can lead to sudden thunderstorms.

What cloud is a characteristic of stable air?
The clearest way to observe the difference between a stable and an unstable air mass is to look at the clouds: A stable atmosphere will have largely flat layers of cloud, which may exhibit some lumpiness but will not extend far upwards. There may be several such layers or, occasionally, clear skies.

What are the general characteristics of unstable air?
Unstable air will generally have tall cauliflower-like clouds known as cumulus. These grow quickly and are associated with showers of heavy rain. Some get so tall that ice forms near their tops, giving a fluffy, bright white appearance to what is called the anvil cloud-head.

What is stable and unstable atmosphere?
In a stable atmosphere, the parcel will return to its original position when the force is removed; in an unstable atmosphere, the parcel will accelerate in the direction of its forced motion; and in a neutrally stable atmosphere, it will remain at its new position.

What is the difference between stable and unstable atmosphere fire?
Stable: If the parcel temperature is equal to or cooler than the environmental temperature, it will stay at its current level or sink. Unstable: If the air parcel temperature is warmer than the environmental temperature, it will rise.
