2. what happened to wind speed in hurricane Katrina as the pressure dropped?

3. As pressured dropped, wind speed increased

4. What happens to a hurricane when it moves over land

5. weakens

6. What happens to a hurricane when it moves warm ocean water

7. Gains strength

8. What happens to a hurricane when it moves cool ocean water

9. weakens

10. Why does a hurricane not continue to gain strength as it moves northeast in the Atlantic Ocean

11. As the hurricane moves NE over the ocean the water becomes cooler & weakens the system

12. What type of weather change does a cold front bring?

13. Cooler temperatures & heavy rains

14. What type of weather change does a warm front bring?

15. Warmer temperatures & steady precipitation

16. How do you know the direction a front is moving?

17. The direction the teeth are facing

18. Draw a cold front symbol

20. Draw a warm front symbol

22. Draw a High pressure symbol

24. Draw a Low pressure symbol

26. What are the lines on a map that show areas of equal pressure and how are they related to wind speed?

27. Isobars – the closer together the stronger the winds

28. What type of weather is associated with a High (H) pressure system
What type of weather is associated with a High (H) pressure system? Explain why

29. Clear & sunny skies

30. What type of weather is associated with a Low (L) pressure system
What type of weather is associated with a Low (L) pressure system? Explain why

31. Clouds & precipitation

32. What is the force that causes a storm to become a hurricane?

33. Coriolis effect

34. Why doesn’t a hurricane form near the equator

35. No coriolis effect

36. Before a storm becomes a hurricane what is it called first

37. Tropical disturbance

38. Using the Saffir-Simpson scale, what category hurricane occurs when wind speeds reach 115 mph?
Category mph Minimal
Category mph Moderate
Category mph Extensive
Category mph Extreme
Category mph Catastrophic

39. Category 3

40. List the order a storm grows to become a hurricane in order from weakest to strongest.

41. Disturbance, Depression, Storm, Category 1-5

42. What is the difference between westerlies & easterlies (trade winds)

43. Westerlies move west to east & above 30 N latitude Easterlies move east to west & below 30 N latitude line

44. What are high altitudes bands of strong winds near the top of the troposphere at the northern and southern boundaries of the prevailing westerlies

45. Jet stream

46. What is the latitude line that divides the trade winds from the Westerlies

47. 30N

48. Predict where the hurricane will most likely hit land and justify your answer using the following terms: dividing line, westerlies, & easterlies

49. Hurricanes are steered westerly by the trade winds below the 30N dividing line & above the line the hurricane is steered east by the westerlies winds

50. What instrument is used to measure wind speed?

51. anemometer
