Which weather problems should be expected beneath a low-level temperature inversion layer when the relative humidity is high?
Smooth air, bad visibility, fog, haze, or low clouds.Explanation: Inversion great are typically shallow great of smooth, steady air close come the ground with negative visibility and also low clouds. B and also C are incorrect because winds and turbulence are characteristics of turbulent air.

You are watching: What is a characteristic of stable air

The temperature to which air should be cooled to come to be saturated.Explanation: it is the an interpretation of dewpoint.
air temperature.Explanation: Temperature mainly determines the maximum quantity of water vapor air have the right to hold. Warmth air have the right to hold much more water vapor than cool air. A is incorrect because air security does not determine exactly how much water vapor air deserve to hold. B is incorrect due to the fact that dewpoint deserve to only identify relative humidity in ~ a given temperature, and boost in temperature would certainly in result raise the amount of water vapor that the air deserve to hold.
Stratiform clouds.Explanation: steady air masses are calm; stratiform clouds space smooth and also they execute not build vertically prefer cumulus clouds. B is incorrect since stable air usually has dust or smoke, i beg your pardon will cause low visibility. C is incorrect because cumulus clouds are a authorize of atmospheric instability.
produce upslope fog (a kind of short cloud).Explanation: Upslope fog occurs as soon as moist, stable air is compelled up sloping land functions like a hill range. Fog is also classified as a form of low cloud formation. B is incorrect because a rain or snow is the properties of rough air. C is incorrect because convective disturbance if the up and down wait movement, which is obviously unstable.
At around what altitude over the surface ar would the pilot intend the base of cumuliform clouds if the surface air temperature is 82 levels F and also the dewpoint is 38 degrees F?
10,000 feet AGL.Explanation: Temperature and also dew points merge at a price of 4.4 degrees F per 1000 feet. For this reason (82-38)/4.4*1000=10,000 feet AGL.
Smooth air.Explanation: attributes of secure air: stratiform clouds, continuous precipitation, smooth air, negative visibility. A and also B are incorrect due to the fact that of the following features of unstable air: cumulus clouds, showery precipitation, turbulence, an excellent visibility.
across a mountain ridge, and the waiting is stable.Explanation: hill waves form when the wind blows perpendicular come a mountain range on the leeward (or downwind) side of the mountains after the wind overcome up and also over the mountain, developing turbulence and also eddies that can "suck" one aircraft right into the next of the hill if flying too closely. A and B space both incorrect due to the fact that the wind operation parallel come the mountain variety in these circumstances, and also mountain waves are less likely to occur.
squall heat thunderstorms.Explanation: Squall heat thunderstorms can produce heavy hail, disastrous winds, or tornadoes.
An wait mass relocating inland indigenous the coast in winter.Explanation: The advection fog is a result of moist air condensing as it moves end a cooler surface.
TroposphereExplanation: most weather wake up in the troposphere, which extends native the surface to 20,000 feet end the poles and also to 48,000 feet end the equator.
Both A and BExplanation: Both cabin pressurization and also the usage of supplemental oxygen are ways to mitigate the risk of hypoxia.
Variations in surface leading to uneven heatingExplanation: different surfaces radiate warm in differing amounts. Plowed ground, rocks, sand, and barren land offer off a big amount the heat; water, trees, and other areas of vegetation have tendency to absorb and retain heat. The resulting uneven heating of the wait creates tiny areas of local circulation dubbed convective currents. Convective currents cause the bumpy, rough air sometimes experienced when flying at reduced altitudes during warmer weather.
heat exchange.Explanation: as water alters from one state come another, one exchange of heat takes place.
The wind in ~ 5,000 feet AGL is southwesterly while the surface ar wind is southerly. This distinction in direction is primarily due to
friction between the wind and the surface.Explanation: Differences in between the surface of continents and also oceans, and other factors such as frictional forces caused by the topography that the Earths surface ar modify the motion of the waiting in the atmosphere.
Warming from below.Explanation: Cooler air wants to stay near the ground and warmer air want to climb up. Warming increase the waiting from listed below will constantly rise the bottom air up which provides the air less stable. B is incorrect because it will make the air more stable. C is incorrect due to the fact that humid air is lighter 보다 dry air, therefore decreasing the water vapor will let the air more heavier and much more stable.
Turbulence and good surface visibility.Explanation: that is easy to associate turbulence with unstable air. B is incorrect since stable waiting usually contains dust or smoke, which will reason low visibility. So unstable air will have good visibility in contrast. C is incorrect because nimbostratus clouds space dark, low-level clouds through precipitation the exist in secure air.
unstable, moist air.Explanation: To type cumulonimbus clouds (thunderstorm), turbulent air, high humidity, and also lifting action are necessary.
High humidity, lifting force, and also unstable conditions.Explanation: To form a thunderstorm (cumulonimbus clouds), turbulent air, high humidity, and lifting action are necessary.
Warm, moist air end low, flatland areas on clear, calm nights.Explanation: Radiation fog can happen when clear sky, small or no wind, and a little temperature/dew suggest spread.
If the temperature/dewpoint spread out is tiny and decreasing, and also the temperature is 62 F, what type weather is most most likely to develop
Fog or short clouds.Explanation: once the temperature and also dew point are close, and the temperature is over freezing, the is more likely to type fog.
Down 2 levels Celsius per 1,000 feetExplanation: The typical lapse rate is minus 2 levels per 1,000 feet the altitude gain.
7.4 lb/sq inExplanation: at 18,000 feet, the load of waiting is 7.4 lb/sq in, practically 50% than at sea level.

Unstable, clouds and also precipitationExplanation: wait flows right into a low push area to replace rising air. This air often tends to be unstable, and usually brings raising cloudiness and precipitation. Thus, negative weather is commonly linked with locations of short pressure.
