Using Figure A, answer the following questions. (5pts)
11. The most common tornadoes are seldom noticed. How do you think those tornadoes would be classified on the
Fujita scale? Why might they go unnoticed?
12. Contrast the damage done to trees by F0-F1 tornadoes and F2-F3 tornadoes.
13. What should you do if you are in a car and the National Weather Service issues a tornado warning for your area?
Using Figure C, answer the following questions. (5pts)
14. On the diagram above, label the fronts as either cold or warm and the type of clouds you expect to see at each
front.
15. Describe the weather you would expect to see at the warm front
16. Describe the weather that would occur after the cold front passed by.
17. Explain what happens to the air masses at a cold front that can cause clouds to form.
Using the Figure B, answer the following questions. (5pts)
18. What are the lines that have numbers on the map? What do they tell you about the weather?
19. Look at our current weather map: Please tell me where the stationary, cold front, and warm front is. Also, please
identify which state has clear skies and which state has stormy weather and why. And which direction is the air
moving?
20. Which direction is the highest wind blowing from? Which state has the highest winds?
21. Draw a wind barb showing a northern wind blowing at 30 knots with 75% cloud cover.
Using Figure D, answer the following questions. (5 pts)
22. Calculate how cold it feels if the temperature is 20 degrees F and the wind is blowing 15 miles per hour. Wind
chill = ________
23. Calculate how cold it feels if the temperature is 40 degrees F and the wind is blowing 24 miles per hour. Wind
chill = ________
EXTENDED RESPONSE (6 Points)
24. Think about the sources of weather data presented in this chapter. Choose three of them to discuss. Which of
those sources would provide the best information about development and movement of a hurricane? Explain
why the source would be used and why the other two sources would or would not be used for this purpose.
HINT: to receive 6 points you need to have a response that demonstrates an understanding of the problem by
correctly identifying satellite data as the best source. Describe the types of data gathered by satellites. Identifies
two other sources (radar stations, ground stations, weather balloons, weather buoys, or air planes and ships),
describes the type of data they gather, and explains why they would or would not be used for tracking a
hurricane.
