Meteorology 2 Review 1. 1 2. 3 3. 2 4. 1 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. Identify the type of front shown below. Warm front 8. Identify the type of front shown below. Cold front 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 11. What type of front is shown below? 12. Describe the temperature change Indianapolis will experience soon. 11. Warm front 12. Cooler warmer temps 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 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 19. What type of front can be found close to point D? • Cold front 20. Which of these fronts would you expect to have greater precipitation, but be short lived as the front passes? • Cold front 21. If there is a big H on the weather map where you live, would you expect fair or stormy weather? • fair H 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 26. 2 27. 2 28. Using your RH chart find the following: a. Dry Bulb: 16 Wet bulb: 5 7% b. Dry Bulb: 10 Wet bulb: 8 76% 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 32. 3 33. 1 34. 2 35. evaporation condensation precipitation runoff 36. 2 37. e c d a b 38. 1 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 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. 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. 45. WHICH WAY WILL WIND MOVE? 46. At what point is the wind the strongest? B A 47. Which type of breeze is represented in the diagram below? Where is the high pressure area? Where is the low pressure area? 48. Which type of breeze is represented in the diagram below? Where is the high pressure area? Where is the low pressure area? 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 [ORIGIN from Greek anemos ‘wind’] [ORIGIN from Greek baros ‘weight’] rainy 53. A low pressure system brings Cloudy, ___________ weather. 54. A high pressure system brings clear __________ weather. 55. As the air temperature gets warmer the air decreases pressure ___________. decreases 56. The higher up you go air pressure ___________. 57. A ____________________ measures air barometer pressure. 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 60. 4 61. Evacuate Purchase nonperishable food, stock up on supplies Tie down loose items. 62. 1 63. 3 64. 3 65. 1 3 66. Precipitation/rain Syracuse did not experience a cold front yet. Its in a warm air mass. 67. 4 68. 2 69. Its near a high pressure system. 70. Precipitation/rain east 71. 4 72. 4 73. Draw a station model with the info below. •Cloudy, •52°F •48°F = DP, •pressure is 1010.2 mb •wind speed 15 mph, from NE. 74. What is the pressure of this station in millibars? 1010.2 mb 75. a. What is the temperature? •88°F b. What is the dewpoint? •86°F c. What is the pressure in millibars? •1086.2 mb d. How much precipitation fell in the past 6 hours? •0.35 in 76. a. Is this a low or high pressure system? b. Describe the weather at A, B and C. a. low b. A = cloudy,rain, B = partly cloudy, rainy, C= partly cloudy, drizzle 77. A. What is the wind speed and direction? B. What is this feature? A. Northeast B. Cold front C. What is the air pressure? C. 1008 78. a 1 b 1 79. a b c 2 4 1 80. It is colder and drier because it formed over land and came from the north, while zone B formed over the water closer to the equator. Northeast Precipitation/rain 81. Are these high pressure or low pressure systems? How can you tell? C A B A. High = pressure increases as you move into the center B & C. Low = pressure decreases as you move into the center 82.
