What are some characteristics of unstable air quizlet?
What are characteristics of unstable air? Turbulence and good surface visibility. Explanation: It is easy to associate turbulence with unstable air.
What are characteristics of an unstable air mass?
Unstable air masses have cumuliform clouds which are clouds that stretch vertically up and down. They have staggering precipitation rather than having steady precipitation. They have rough air that causes turbulence and they have good visibility unless there are blowing obstructions in the air.
What are the characteristics of stable and unstable air?
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 indicates unstable air?
Air is considered unstable, in the lowest layers of an air mass when the air is warmer and or more humid than the surrounding air. When this occurs the air will rise, as that air parcel is warmer than the air surrounding it. In an unstable environment, the weather can change suddenly and can be violent.
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.
What are characteristics of a moist unstable air mass Part 107?
What are characteristics of a moist, unstable air mass? Cumuliform clouds and showery precipitation. If an unstable air mass is forced upward, what type clouds can be expected? Clouds with considerable vertical development and associated turbulence.
What is stable and unstable 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.
What are four characteristics of stable air?
Explanation: characteristics of stable air: stratiform clouds, continuous precipitation, smooth air, poor visibility. A and B are incorrect because of the following characteristics of unstable air: cumulus clouds, showery precipitation, turbulence, good visibility.
What’s the difference between stable air and unstable 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.
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 properties does Stable air have?
The Characteristics of Stable Air Mass
- Cloud Cover. Because stable air masses are, by nature, calm and free of violent disturbances, they are often marked by the appearance of stratiform clouds or fog. …
- Smooth Air. …
- Uninterrupted Precipitation. …
- Low Visibility.

What type of weather is associated with unstable 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.
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.
What are the factors that affect the stability of air?
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.
What is the difference between stable and unstable 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.
What kind of weather is associated with 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.
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.
