1. What is a measure of water
vapor in the air? Humidity
2. What is the amount of water
vapor in the air at a given
temperature expressed as a
percentage of the maximum
amount of water vapor the air
can hold at that temperature?
Relative humidity
3. What is a condition in which
the upper regions of the
atmosphere are warmer than
the lower regions?
Temperature inversion
4. What is the condensation of
water droplets above the
earth’s surface? Clouds
5. What is an air-circulation
pattern in which air warmed
by the ground rises while
cooler air aloft sinks?
Convectional lifting
6. What is the lifting of air over a
topographic barrier such as a
mountain? Orographic lifting
7. What is the contact zone
between two different air
masses? Front
8. What is the lifting that occurs
as two air masses converge?
Frontal lifting
9. What is the difference between
a cold front and a warm front?
10. Explain how convectional
lifting plays a role in the
formation of cumulus clouds.
11. Are clouds having vertical
development characteristic of
stable air, stationary air,
unstable air, or dry air?
12. Explain how clouds form.
13. What is a temperature
inversion? Give examples of
where these inversions may
occur.
14. Does a rising parcel of air get
warmer, cooler, or stay the
same temperature?
15. What happens to the water
vapor in saturated air as the air
cools?
16. As air temperature decreases,
does relative humidity
increase, decrease, or stay the
same?
17. What is the difference
between humidity and relative
humidity?
18. What cloud form is
associated with
thunderstorms?
19. How do downdrafts form in
thunderstorms?
20. Briefly describe how thunder
and lightning develop.
21. What information must be
known to predict the weather?
22. Why do clouds tend to form
above mountain peaks?
23. Why does warm, moist air
blowing over cold water result
in fog?
24. Why does dew form on the
ground during clear, calm
summer nights?
25. Why does a July day in
Alabama generally feel much
hotter than a July day in TX.
26. What is the source of the
enormous amount of energy
released by a hurricane?
27. Why are clouds that form
over water more efficient in
producing precipitation than
clouds that form over land?
28. How does a rain-shadow
desert form?
29. Explain why freezing rain is
more commonly associated
with warm fronts than with
cold fronts.
30. How do fronts cause clouds
and precipitation?
31. What is the difference
between rainfall that
accompanies the passage of a
warm front verses a cold
front?
32. Why don’t cumulus clouds
form over cold water?
33. What accounts for the large
spaces of blue sky between
cumulus clouds?
34. How do tornadoes form?
35. Give some statistical data on
tornadoes and thunderstorms.
