What are characteristics of stable air?

What are characteristics of stable air?

What are the characteristics of stable air? A—Good visibility; steady precipitation; stratus clouds. B—Poor visibility; steady precipitation; stratus clouds.

What is the definition of stable air?

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 kind of weather 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.

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 characteristics of stable air quizlet?

Explanation: characteristics of stable air: stratiform clouds, continuous precipitation, smooth air, poor visibility.

What causes stable air?

The atmosphere is said to be absolutely stable if the environmental lapse rate is less than the moist adiabatic lapse rate. This means that a rising air parcel will always cool at a faster rate than the environment, even after it reaches saturation.

Does stable air rise?

Air that has a tendency to sink is known as a stable air. If the air parcel's temperature is greater than the temperature of the surrounding air mass, the air parcel is less dense and tends to rise.

Is unstable air smooth?

The usual convection in unstable air gives a “bumpy” ride; only at times is it violent enough to be hazardous. In stable air, flying is usually smooth but sometimes can be plagued by low ceiling and visibility.

Which of the following is a characteristic of a stable air mass?

Explanation: characteristics of stable air: stratiform clouds, continuous precipitation, smooth air, poor visibility.

How does stable air differ from unstable air?

Stable air resists upward movement, whereas unstable air does not. Clouds formed when stable air is forced to rise are generally thin and precipitation, if any, is moderate or light. Conversely, when unstable air rises, clouds are often towering and precipitation can be heavy.

What makes air stable or unstable?

The atmosphere is said to be absolutely stable if the environmental lapse rate is less than the moist adiabatic lapse rate. This means that a rising air parcel will always cool at a faster rate than the environment, even after it reaches saturation.

What is the difference between stable and unstable 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.

How is stable air formed?

If the air parcel is colder than the environment in its new position, it will have higher density and tend to sink back to its original position. In this case, the air is stable because vertical motion is resisted.

What does it mean if air is stable or unstable?

Weather is strongly affected by how stable or unstable the atmosphere is. 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.
