Horizontal Rule

1. What scale is used to measure the intensity and danger of a hurricane?

Saffir-Simpson
Modified Mercalli
Doppler
Richter
Fujita-Pearson
2. Hurricanes form most frequently:
Over land masses in middle latitudes
Over the poles
Over warm tropical oceans
Over tropical land masses
At the equator
3. Which one of the following has the strongest winds?
Hurricanes
Midlatitude cyclones
Typhoons
Tornadoes
4. Which one of the following is a FALSE statement about tornadoes?
They are most common in the Midwest and Great Plains states.
They occur mostly in late fall and winter.
They are associated with cumulonimbus clouds.
They often occur in advance of a cold front of a midlatitude cyclone.
They generally move from southwest to northwest.
5. Following the passage of a cold front through the San Francisco Bay Area, we can expect:
Persistent rain and drizzle
Low pressures and strong winds
Clearing skies and cooler temperatures
Warm, muggy weather with low clouds
6. Warm front weather lasts longer than cold front weather because:
A warm front has a low angle slope and covers a greater area with its weather.
There is more water in the warm air.
A warm front involves only warm air.
Winds in a warm front shift more frequently than those in a cold front.

    The following question (question 7) refers to this diagram of a weather front symbol:
    Diagram of a weather front symbol used on a weather map.

7. The weather front symbol shown above is a(an):
Cold front
Warm front
Stationary front
Occluded front
8. What happens when a cold front overtakes a warm front?
The two fronts dissolve
Cloud formation ceases
An occluded front forms
A stationary front forms
9. Air masses that originate in the Gulf of Mexico are:
Continental Tropical (cT)
Maritime Tropical (mT)
Maritime Polar (mP)
Continental Polar (cP)
Equatorial (E)
10. Midlatitude cyclones commonly develop along a feature called the:
Subtropical jet stream
Equatorial trough
Intertropical convergence zone
Polar front
11. A cold front is a:
Mass of cold air
Zone of below freezing temperatures
Zone of contact where warm air gains ground over a cold air mass
Zone of contact where cold air gains ground over a warm air mass
12. In what part of the United States are thunderstorms most frequent?
The Pacific Northwest
The Central and Southern States
Western Canada
California
13. If you were to look up at the sky and see cirrus clouds followed by altostratus, and then stratus clouds you would be observing the passage of:
A warm front
A cold front
An anticyclone
All of the above
14. As a cyclone progresses through its life cycle and the cold front catches up with the warm front, the pie-slice wedge shape of warm, moist air in the storm system:
Increases in size
Decreases in size
Remains the same size
15. Which one of the following fronts moves fastest?
Cold fronts
Warm fronts
Occluded fronts
Stationary fronts
