Which of the following is a characteristic of stable air?
Explanation: The following are characteristics of stable air: stratiform clouds continuous precipitation smooth air poor visibility.
Which is a characteristic typical of a stable air mass group of answer choices?
What is a characteristic of stable air? Stratiform clouds. Explanation: Stable air masses are calm; stratiform clouds are smooth and they do not build vertically like cumulus clouds.
What is 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 is associated with stable air?
Stable air means that the weather is likely to be calm. It may rain or snow slowly and steadily it may be sunny but the weather will not change quickly. Unstable air means that the weather might change quickly with very little warning. Unstable air leads to sudden thunderstorms.
Which air mass is more stable?
If warm air is over cold air, this is stable. If cold air is over warm air this is unstable. For this reason, tropical air masses are usually less stable than polar air masses.
What conditions cause a stable air mass quizlet?
Indicates stability: stability of the atmosphere is determined by vertical movements of air. Warm air rises when the air above is cooler. Cooling from below: surrounding air is warmer, which would increase the stability of an air mass.
What is a characteristic of stable air cloud?
What are the characteristics of stable air? A—Good visibility; steady precipitation; stratus clouds. B—Poor visibility; steady precipitation; stratus clouds.
What are the characteristics of stable air pilot?
Stable Air vs Unstable Air
| Stable Air | Unstable Air | |
|---|---|---|
| Icing | Rime, freezing rain, or clear ice | Moderate to heavy clear ice |
| Visibility | Restricted for long periods | Good, outside areas of precipitation |
| Other | Frost; dew; temperature inversions; little or no turbulence | High and/or gusty winds; potential for turbulence; lightning |
Is stable air turbulent?
People flying through stable air masses will not experience violent turbulence or disturbances as they would in unstable air masses. The undisturbed air is free to flow over the wing optimally and is not interrupted.
What are the stable characteristics of the atmosphere?
Three characteristics of the sounding then determine the stability of the atmospheric layer in which the parcel of air is embedded. These are: (1) The temperature lapse rate through the layer; (2) temperature of the parcel at its initial level; and (3) initial dew point of the parcel.
How do you know if a air is stable or unstable?
Once we have lifted the air we let go of the parcel and watch to see what happens next. If the air comes back to where it started, the atmosphere is stable. If the air continues to rise the atmosphere is unstable. In the figure above the air in the parcel has ended up colder and denser than the surrounding air.
How can you determine the stability of an air mass?
To determine the stability of an air parcel, one compares its temperature to the temperature of the surrounding air mass. If the air parcel's temperature is less than the temperature of the surrounding air mass, it is denser than the surrounding air and therefore has a tendency to sink.
How can you determine the stability of an air mass quizlet?
Indicates stability: stability of the atmosphere is determined by vertical movements of air. Warm air rises when the air above is cooler. Cooling from below: surrounding air is warmer, which would increase the stability of an air mass.
