6. For each air mass below, identify its name, and
describe the weather in each one.
A. cP
• Dry and cool
B. cT
• Dry and warm
C. mP
• Humid and cool
D. cT
• Humid and warm.
7. Identify the type of front shown below.
Warm front
8. Identify the type of front shown below.
Cold front
9. What type of front is shown below?
10. Describe the type of weather Columbus
will experience in a few days.
9. Cold front
10. Brief, heavy rain, followed by cooler temps
11. What type of front is shown below?
12. Describe the temperature change
Indianapolis will experience soon.
11. Warm front
12. Cooler  warmer temps
13. The boundary between two air masses
is a ____.
• front
14. A cold air mass meets and pushes a
warm air mass out of the way. What
type of front am I?
• Cold front
15. A warm air mass is trapped between
to cold air masses. What type of front
am I?
• Occluded front
16. A warm air mass meets and pushes a
cold air mass out of the way. What
type of front am I?
• Warm front
17. I am a front that brings drizzly rain
and am followed by warm clear
weather.
• Warm front
18. A cold air mass meets a warm air but
neither is very strong. They are
separated and many days of wet ,
cloudy weather occur.
• Stationary front
19.
What type of
front can be found
close to point D?
• Cold front
20.
Which of these
fronts would you
expect to have
greater
precipitation, but
be short lived as
the front passes?
• Cold front
21.
If there is a big H
on the weather
map where you
live, would you
expect fair or
stormy weather?
• fair
H
22. What process forms clouds?
• condensation
23. Explain the difference between cirrus clouds and
cumulus clouds.
• Cirrus clouds are light and feathery while
cumulus are big and puffy
24. How does water from lakes and oceans enter the
atmosphere?
• evaporation
25. How does ice that melts up in the mountains
travel back to large bodies of water?
• runoff

28. Using your RH chart find the
following:
a. Dry Bulb: 16
Wet bulb: 5
7%
b. Dry Bulb: 10
Wet bulb: 8
76%
29. How does temperature affect
humidity?
• As temp increases, humidity increases
30. Explain what it means when the
relative humidity is at 40%.
• The air is holding 40% of the air it
can possible hold at that temp
31. What instrument is used to measure
relative humidity?
• psychrometer

39. What instrument measures air pressure?
What unit is used?
• Barometer, millibars
40. How does elevation affect air pressure?
• As elevation increases, pressure decreases
41. Which is more dense: cold air or hot air?
• cold
42. Which has more air pressure: cold air or
hot air?
• Cold
43.
In a high pressure area,
air will (rise, sink)
because the air is
(less, more) dense.
This is because the air is
(cold, warm)
and (rises, sinks).
Therefore, clouds CANNOT form.
44.
In a low pressure area,
air will (rise, sink)
because the air is
(less, more) dense.
This is because the air is
(cold, warm)
and (rises, sinks).
Therefore, clouds are
LIKELY to form.
45. WHICH WAY WILL WIND MOVE?
46. At what
point is the
wind the
strongest?
B
A
47.
Which type of breeze is represented in the
diagram below?
Where is the high pressure area?
Where is the low pressure area?
48.
Which type of breeze is represented in the
diagram below?
Where is the high pressure area?
Where is the low pressure area?
49. How are weather conditions in a high
pressure system different than those in a low
pressure system?
• High pressure = clear, fair weather
• Low pressure = cloudy, rainy
50. Describe wind direction in a high pressure
system.
• High pressure = clear, fair weather
51. Why do global winds curve?
• Because the earth rotates
[ORIGIN from Greek anemos ‘wind’]
[ORIGIN from Greek baros ‘weight’]
rainy
53. A low pressure system brings Cloudy,
___________
weather.
54. A high pressure system brings clear
__________
weather.
55. As the air temperature gets warmer the air
decreases
pressure ___________.
decreases
56. The higher up you go air pressure ___________.
57. A ____________________
measures air
barometer
pressure.
58. Wind always moves from
_________ pressure to
__________ pressure.
• High, low
59. On a pressure map, closely spaced
isobars means that you will have
_______ winds.
• Strong/fast
