Clouds are ______ to develop if a radiosonde sounding indicates unstable air. more likely
In an agricultural field, direct evaporation of water from the soil is usually ______ transpiration of water by plants. less than
If the air temperature is 12 °C and the vapor pressure is the same as the saturation vapor pressure, the relative humidity is 100%
Air mass advection ______ change the relative humidity. can
On a clear and calm day, the relative humidity usually ______ between sunrise and early afternoon. falls
Rising air temperature causes the saturation mixing ratio to ______ increase
The maximum pressure that water vapor molecules could exert if the air were saturated is called the saturation vapor pressure.
As the temperature of a saturated (cloudy) air parcel falls, its relative humidity ______. does not change
A temperature inversion is characterized by a(n) ______ of air temperature with altitude. increase
Conditional stability indicates that an air layer is unstable for saturated and stable for unsaturated air parcels.
An example of sublimation is ice disappearing while temperatures remain below freezing.
A lapse rate of ______ Celsius degrees per 1000 meters is stable for unsaturated air parcels. All of these are correct.
The saturation vapor pressure ______ with rising air temperature. increases
If the temperature of an unsaturated (clear) air parcel does not change while its mixing ratio increases, the density of the parcel ______. decreases
In an isothermal temperature profile, the air temperature does not change with altitude.
Conditional stability indicates that an air layer is unstable for cloudy and stable for clear air parcels.
If a saturated (cloudy) air parcel is heated (say by absorption of radiation), its relative humidity ______. decreases
______ air tends to suppress convection. Stable
If the mixing ratio of a parcel of air is 2 grams per kilogram and its saturation mixing ratio is 6 grams per kilogram, the relative humidity is ______ percent. 33.3
If the mixing ratio of a parcel of air is 6 grams per kilogram and the relative humidity is 25 percent, the saturation mixing ratio is ______ grams per kilogram. none of these is correct
As an aircraft ascends within the troposphere, the external None of the above is correct.
Two equal volumes of air have the same temperature and pressure. One contains more water vapor than the other. Both volumes of air contain the same number of gaseous molecules
In winter, the precipitable water value is likely to be highest in ________. Miami, FL
Two equal volumes of air at the same temperature and pressure have different amounts of water vapor in them. The air parcel with the higher relative humidity will contain the same number of molecules as the other parcel.
Suppose that the vapor pressure of the cold outside air is the same as the vapor pressure of the warm air indoors. If the door is opened and the cold air replaces some of the warm air, then the new relative humidity indoors would be higher than before.
Unstable air ______ vertical motion of air parcels. enhances
Stable air ______ vertical motion of air parcels. suppresses
______ on a Stüve diagram are isobars. Horizontal lines
A lapse rate of ______ Celsius degrees per 1000 meters is unstable for unsaturated (clear) air parcels. 11
A lapse rate of ______ Celsius degrees per 1000 meters is conditionally stable. 8
A lapse rate of ______ Celsius degrees per 1000 meters is stable for clear air and unstable for cloudy air. 7
If the air temperature drops with altitude such that the actual lapse rate (sounding) is 7 Fahrenheit degrees per 1000 feet, the air layer is ______ for saturated (cloudy) air parcels and ______ for unsaturated (clear) air parcels. unstable...unstable
Rising parcels of saturated (cloudy) air do not cool as rapidly as rising parcels of unsaturated (clear) air because expansional cooling of saturated air is partially compensated for by release of latent heat.
A snow cover tends to ______ the overlying air. stabilize
A relatively warm surface tends to ______ the overlying air. destabilize
All of the following soundings (temperature profiles) always indicate stable atmospheric conditions with the exception of a drop of temperature with altitude.
Normally, the stratosphere is ______. stable
Cumulus clouds are more likely to form over vegetated land surface in summer.
As saturated (cloudy) air flows up the windward slopes of a mountain range, the saturation mixing ratio decreases.
As unsaturated (clear) air flows down the leeward slopes of a mountain range, All of the above are correct.
As an unsaturated parcel of air ascends dry adiabatically, None of the above is correct.
A rain shadow is situated downwind from the ______ slopes of a high mountain barrier. leeward
Cumulus clouds are ______ likely to build into thunderstorm clouds when the air temperature profile (sounding) indicates unstable conditions. most
