Question
1. Suppose a parcel of cool air has a temperature and dew point of 40F, while a parcel of hot air has a temperature of 100F and a dew point of 25F. The hot air contains ________ water vapor than the cold air, and the cold air has a ________ relative humidity.
a. less, lower
* b. less, higher
c. more, lower
d. more, higher
e. more, similar
2.
If cold outside air of temperature 10°F is brought indoors and warmed with no change in its water vapor content, the relative humidity of this air will ________ and the dew point will ________.
a. increase, decrease
b. decrease, remain the same
c. increase, remain the same
d. decrease, increase
e. decrease, decrease
3.
a. is the level at which rain falling from a cloud evaporates.
b. represents the highest level to which air can be forced to rise by a mountain.
c. is a function only of the temperature of rising air.
d. is the altitude at which the temperature in a rising parcel of air falls to the dew point.
4.
On average, higher afternoon summertime temperatures can be found at ________ latitudes, ________ elevations and ________ large bodies of water.
a. higher, lower, close to
b. lower, higher, close to
c. higher, lower, far from
d. lower, lower, far from
e. lower, lower, close to
5.
When considering only incoming solar radiation and outgoing infrared radiation, regions within about 35° latitude of the equator undergo a net ________ and higher latitudes undergo a net ________.
a. cooling, warming
b. warming, cooling
c. warming, warming
d. cooling, cooling
6.
With clear and calm conditions, the air next to the ground is usually ________ the air above during the night, and ________ the air above during the day.
a. colder than, warmer than
b. colder than, colder than
c. warmer than, colder than
d. warmer than, warmer than
e. the same temperature as, the same temperature as
Explanation / Answer
1. Answer b. less, higher
2. Answer b. Decrease, remain the same (increase in temperature means lowering the RH. And as the air temperature increases, with no addition of water vapour to the air, the dew point will remain the same)
3. Answer d. Is the altitude at which the temperature in a rising parcel of air falls to the dew point (It is the height at which the relative humidity (RH) of an air parcel will reach 100%)
4. Answer d. Lower, lower, far from
5. Answer b. Warming, cooling
The further away from the equator that you are the less sunlight that the location receives.
6. Answer a. Colder than, warmer than
