Spotter Network Test 1
1. The following symbol represents which type of frontal y?: Occluded
boundar
2. Which air mass source regions influence the weather of
the continental
U.S.?: Polar Regions, tropical regions, Continental Regions
3. Most weather frequently occurs of air
masses.: Along the boundary
4. A key air mass type influencing summer weather and
climate in Louisiana is .: Maritime Tropical (mT)
5. At the surface, what are signs indicating a front?: The
"convergence" or coming together of winds, a change in
temperature, a change in pressure
6. The number of atoms and molecules that make up the
layers of the atmos- phere changes based on elevation. The
,first 18,000 feet of the atmosphere contains about
of the air molecules.: 50%
7. Which two units are commonly used to measure air
pressure in the United
States?: millibars, inches of mercury
8. What other variables can influence air pressure besides
change in eleva- tion?: radiation (heating) from the sun, weather
systems
9. In which region would you expect very little or minimum
change in air pressure excluding tropical cyclones?: tropics
10. is calculated as the change in pressure
between two lo- cations divided by the change in the distance
of those two locations: Pressure Gradient Force
11. Why does Florida experience fewer hailstorms when
compared to Col- orado, New Mexico, and Wyoming?: Lower
number of thunderstorms
,12. Which meteorological hazard is produced as a result of a
sudden dis- charge or charge separation in a cloud?:
lightening
13. According to the figure below, which region exhibits the
most thunder- storm days per year?: Midwest
14. Which of the following hazards can be produced by a
thunderstorm?: Tor- nados, lightening, hail, blizzards, ice storms,
dust storms
15. What color is used to graphically identify a high pressure
system on a weather map?: Blue
16. When representing pressure systems graphically on, for
example, a weath- er map, a low pressure system is denoted
by which letter?: L
17. The wind chill temperature index reflects...: The bodies
perception of cold temperature when exposed to wind
18. What are the necessary ingredients or mechanisms that
are needed for a thunderstorm to develop in the atmosphere?:
Moisture, unstable air mass, lifting mechanism
, 19. What moisture sources help explains why there is a
significant amount of rain to fall in the southeastern United
States?: Gulf of Mexico
20. What lifting mechanism forces air upward along a large hill
or mountain- ous barrier which produces cloud formation and
precipitation to form in the atmosphere?: Orographic
21. Place the life cycle stages of a thunderstorm in the
correct order: (A) Mature Stage(B) Cumulus Stage(C)
Dissipating Stage: B-A-C
22. What type of thunderstorm tends to form along or ahead of
a cold front and can produce heavy precipitation, hail,
lightning, strong winds, and possible tornadoes?: supercell
23. Based on the below figure, what is the peak monthly
period for tornadoes to occur with the United States?: April-
June
24. Based on the below figure, what is the peak time period
for tornadoes to occur with the United States?: 3 pm - 7 pm
