QUESTION 1
When water changes phase, what always happens?
Some form of precipitation occurs
The hydrogen bond is broken
A cloud is formed
Latent heat is absorbed or released
QUESTION 2
The saturated adiabatic lapse rate is less than the dry adiabatic lapse rate because:
statement is untrue: they are the same
evaporation warms the dry adiabatic lapse rate
moist air is always warmer than dry air
condensation releases latent heat
condensation absorbs latent heat
QUESTION 3
Which of the following clouds indicates precipitation is occurring?
Stratus
Nimbostratus
Cirrostratus
Altocumulus
QUESTION 4
If water droplets and ice crystals are both present in the same cloud:
the ice crystals will shrink while the droplets grow
the ice crystals will grow while the droplets shrink
both will grow if the temperature is at the dew point
the ice crystals will behave independently of one another
neither the droplets nor the crystals will grow
QUESTION 5
Suppose an air mass cools as it moves over a landmass, but no water vapor is added or lost. The relative humidity will _____ while the specific humidity will _____.
fall/rise
not change/not change
rise/not change
not change/fall
fall/not change
QUESTION 6
The elevation at which a parcel of air becomes saturated is called the _____________.
lifting condensation level
level of free convection
level of atmospheic capacity
level of convective initiation
None of the above
QUESTION 7
If the temperature of an unsaturated parcel of air remains the same, but the vapor content increases, the absolute humidity will:
increase
decrease
change a little
remain the same
QUESTION 8
The Bergeron process describes precipitation by:
ice crystal formation
collision
coalescence
none of the above
QUESTION 9
Which of the following stations has the greatest amount of moisture in the air?
Station A: Relative humidity = 70%
Station B: Specific humidity = 8 g/kg
Station C: Dew point = 50°F
Cannot be determined from the information given
QUESTION 10
Of the three ways of quantifying atmospheric water vapor, only one is unaffected by variations in temperature, pressure, or volume. Because it is a statement of mass per mass, _____________ changes only if the actual quantity of water vapor in a given parcel of air changes:
absolute humidity
specific humidity
relative humidity
no such measure of humidity exists
A.Some form of precipitation occurs
B.The hydrogen bond is broken
C.A cloud is formed
D.Latent heat is absorbed or released
Explanation / Answer
1. Option D, Latent heat is absorbed or released
Latent heat is the energy absorbed or released by a substance during a change in its phase.
2. Option D, condensation releases latent heat.
As vapour condenses into water or water freezes into ice for a saturated parcel, latent heat is released into the parcel
3. Option B, Nimbostratus
They are low lying dark clouds which are accompnied by low to moderate precipitation.
4. Option B, Ice crystals grow while the droplets shrink
Beacuse the vapour pressure over teh ice crystal is lower than that over the water droplet, ice crystals grow at the expense of water droplets.
5. Option E, fall / Not change
Relative humidy will decrease because it measure the current absolute humidity relative to the maximum at that temperature. Specific humidity does not change since it is the ratio of water vapour content of the mixture. Since no water vapour is added or lost, specific humidity will not change
6. Option A, Lifting condensation level
It is the altitude at which the parcel reaches saturation.
7. Option A, Increase
Absolute humidity is a measure of water vapour and hence it will increase when water vapour content increases.
