  4. 5. Identify the air masses below. 2. 4. 1. 3. 6. 8. 5. 7.

  5. What type of air mass would form over each area? Please label. 2. 4. cP mP 3. mP 1. cP 6. 8. 5. cT mT 7. mT mT

  6. 6. For each air mass below, identify its name, and describe the weather in each one. A. cP Dry and cool B. cT Dry and warm C. mP Humid and cool D. cT Humid and warm.

  7. 7. Identify the type of front shown below. Warm front

  8. 8. Identify the type of front shown below. Cold front

  9. 9. What type of front is shown below? 10. Describe the type of weather Columbus will experience in a few days. 9. Cold front 10. Brief, heavy rain, followed by cooler temps

  10. 11. What type of front is shown below? 12. Describe the temperature change Indianapolis will experience soon. 11. Warm front 12. Cooler  warmer temps

  11. 13. The boundary between two air masses is a ____. • front 14. A cold air mass meets and pushes a warm air mass out of the way. What type of front am I? • Cold front 15. A warm air mass is trapped between to cold air masses. What type of front am I? • Occluded front

  12. 16. A warm air mass meets and pushes a cold air mass out of the way. What type of front am I? • Warm front 17. I am a front that brings drizzly rain and am followed by warm clear weather. • Warm front 18. A cold air mass meets a warm air but neither is very strong. They are separated and many days of wet , cloudy weather occur. • Stationary front

  13. 19. What type of front can be found close to point D? • Cold front

  14. 20. Which of these fronts would you expect to have greater precipitation, but be short lived as the front passes? • Cold front

  15. 21. If there is a bigH on the weather map where you live, would you expect fair or stormy weather? • fair

  16. 22. What process forms clouds? condensation 23. Explain the difference between cirrus clouds and cumulus clouds. Cirrus clouds are light and feathery while cumulus are big and puffy 24. How does water from lakes and oceans enter the atmosphere? evaporation 25. How does ice that melts up in the mountains travel back to large bodies of water? runoff

  19. 28. Using your RH chart find the following: a. Dry Bulb: 16 Wet bulb: 5 7% b. Dry Bulb: 10 Wet bulb: 8 76%

  20. 29. How does temperature affect humidity? As temp increases, humidity increases 30. Explain what it means when the relative humidity is at 40%. The air is holding 40% of the air it can possible hold at that temp 31. What instrument is used to measure relative humidity? psychrometer

  28. 39. What instrument measures air pressure? What unit is used? Barometer, millibars 40. How does elevation affect air pressure? As elevation increases, pressure decreases 41. Which is more dense: cold air or hot air? cold 42. Which has more air pressure: cold air or hot air? Cold

  29. 43. In a high pressure area, air will (rise, sink) because the air is (less, more) dense. This is because the air is (cold, warm) and (rises, sinks). Therefore, clouds CANNOT form.

  30. 44. In a low pressure area, air will (rise, sink) because the air is (less, more) dense. This is because the air is (cold, warm) and (rises, sinks). Therefore, clouds are LIKELY to form.

  31. 45. WHICH WAY WILL WIND MOVE?

  32. 46. At what point is the wind the strongest? A B C A B D

  33. Which type of breeze is represented in the diagram below? Where is the high pressure area? Where is the low pressure area? 47. Sea Breeze (daytime) H L

  34. Which type of breeze is represented in the diagram below? Where is the high pressure area? Where is the low pressure area? 48. Land Breeze (night time) L H

  35. 49. How are weather conditions in a high pressure system different than those in a low pressure system? • High pressure = clear, fair weather • Low pressure = cloudy, rainy 50. Describe wind direction in a high pressure system. • High pressure = clear, fair weather 51. Why do global winds curve? • Because the earth rotates

  36. 52. What instrument is used to measure: a. wind speed b. air pressure anemometer barometer [ORIGIN from Greek anemos‘wind’] [ORIGIN from Greek baros‘weight’]

  37. Cloudy, rainy clear 53. A low pressure system brings ___________ weather. 54. A high pressure system brings __________ weather. 55. As the air temperature gets warmer the air pressure ___________. 56. The higher up you go air pressure ___________. 57. A ____________________ measures air pressure. decreases decreases barometer

  38. 58. Wind always moves from _________ pressure to __________ pressure. • High, low 59. On a pressure map, closely spaced isobars means that you will have _______ winds. • Strong/fast
