Air masses may extend 1600 km or more across

Air masses are usually several...

Humid and warm 
3
The classification of air mass types is based on which parameter?
 
Source region
4
Which type of air mass is responsible for depositing large quantities of lake-effect snow during...
 
Continental polar air mass
5
 a maritime tropical air mass is headed toward the city. What type of weather would you...
 
warmer and wetter than usual 
6
What is a front? 
 
the boundary between two air masses of different temperatures
7
Where does rain occur in a warm front?
 
Rain occurs along and in front of a warm front.
8
Rain occurs along and behind a cold front.
 
Rain occurs along and behind a cold front.
9
How are rain patterns different near warm and cold fronts?
 
Rain near a cold front occurs over a smaller spatial area and is more intense than near a warm...
10
What determines whether a front is called a cold front or a warm front?
 
The type of front is determined by which air mass is moving.
11
Why does rain occur near a cold front?
 
Rising warm air cools, resulting in cloud formation and rain.
12
Why does rain occur near a warm front?
 
Rising warm air cools, resulting in cloud formation and rain
13
When the ground position of a front moves so that warm air occupies territory that was previously...
 
warm front 
14
When cool air rapidly displaces the warmer air along a cold front, which cloud type is produced?
 
cumulonimubs
15
The advance of which type of air mass produces most cold fronts that develop in the United...
 
continental polar air mass
16
What is the result when a warm front is squeezed upward between two cold fronts, producing...
 
The result is an occluded front 
17
As a cold front moves into a region, which weather pattern is likely to result?
 
severe thunderstorms, high winds, heavy rains, and hail
18
What happens when warm air collides with a cold front?
 
Warm air moves up and over a cold air mass.
Warm air forms cumulonimbus clouds and produces...
19
Which types of air masses must interact for a low-pressure system to develop in the middle...
 
maritime tropical and continental polar
20
As a warm front in a middle-latitude cyclone moves toward a region, what weather conditions...
 
falling pressure and rising temperature
21
As a middle-latitude cyclone pushes a cold front through a region, what type of weather pattern...
 
thunderstorms and cumulonimbus clouds
22
Which type of clouds most often develops with the passing of a warm front over a region and...
 
nimbostratus
23
As a cold front associated with a middle-latitude cyclone passes over a region, which type...
 
heavy rain that passes quickly
24
Which atmospheric feature drives middle-latitude cyclones that produce cold and warm fronts...
 
low-pressure systems
25
In which season do middle-latitude cyclones typically generate the most severe weather in North...
 
Spring
26
Typically, in which direction do middle-latitude cyclones move when crossing the North American...
 
west to east
27
Middle-latitude cyclones typically have both warm and cold fronts associated with them. If...
 
an occluded front
28
In North America, which two types of air masses interact to create middle-latitude cyclones?
 
continental polar and maritime tropical
29
What are midlatitude cyclones?
 
migrating low-pressure cells that move in the band of the westerlies
30
What happens when air masses of different temperatures meet?
 
Well-defined boundaries form between the air masses.
31
Which of the following statements about movement in midlatitude cyclones are accurate?
 
Surface winds move counterclockwise

The cold front advances faster than the...
32
What is occlusion in a midlatitude cyclone?
 
Occlusion is the process by which a cold front overtakes a warm front.
33
When do midlatitude cyclones stop producing storms?
 
when the cold front has completely taken over the warm front
34
What are the three stages of thunderstorm development?
 
cumulus, mature, and dissipating
35
What is a tropical cyclone?
 
a low-pressure disturbance that develops over warm, tropical waters
36
Where are tropical cyclones found?
 
lower and middle latitudes
37
Which of the following names mean "tropical cyclone"?
 
cyclone, typhoon, hurricane
38
Why is heavy rain associated with hurricane formation?
 
Rising, moist air cools. As air cools, water condenses and eventually falls.
39
Why is warm, moist air considered the "fuel" for a hurricane?
 
Air warms as it rises. As air warms, liquid water will evaporate out as water vapor. Evaporation...
40
How big can the diameter of a hurricane become?
 
500 miles
41
What other natural hazards are associated with tornado formation?
 
Thunderstorms 
42
Why does air spiral parallel to Earth's surface during initial stages of tornado formation?
 
Because of friction, surface winds move more slowly than winds higher in the air column.
43
What can cause the horizontally rotating air spiral to become the vertical spiral of a tornado?
 
Updrafts associated with thunderstorm clouds can tilt the horizontal column of spinning air.
44
How are mesocyclones and tornadoes related?
 
Mesocyclones can turn into funnel clouds. A funnel cloud that touches the ground is called...
45
What has steepest pressure gradient? 
 
Tornado
46
Tornadoes most often move TOWARDS what direction?
 
northeast 
47
A cT air mass is ________.
 
warm and dry
48
An mP air mass is ________.
 
cold and humid 
49

51
When an active cold front overtakes a warm front ________.
 
an occluded front forms
52
The electrical discharge of lightning rapidly heats the air, which in turn causes it to expand...
 
thunder
53
Typhoon is another name for a ________.
 
hurricane
