17.How do scientists express the amount of water vapor in the atmosphere? ______________________________________________________________________________

18.Relative Humidity is measured with this instrument:

a. electric hygrometer c. psychrometer

b. hair hygrometer d. all of the above

When reading a psychrometer you are comparing the difference between the (19)___________________________ bulb and the (20)________________________ bulb.

21.When does the wet bulb temperature on a psychrometer lower (cool) the most?

a. when it is dry outside c. when it is raining outside

b. when it is humid outside d. when it is cloudy outside

22.If the difference between the thermometer readings is 5 degrees Celsius and the dry-bulb temperature is 12 degrees Celsius what is the relative humidity? (hint use chart of page 481)

__________________________________________________________________________

Meteorologists use (23)________________________ humidity to express the actual amount of moisture in the air. Specific humidity is not affected by (24)___________________________ like relative humidity is.

The temperature to which air must be cooled to reach saturation is called the (25)___________________ ___________________.

26.What happens to water when the temperature is lower than the dew point?

______________________________________________________________________________

27.What does the dew point temperature depend on? ___________________________________

28. T F Dew is likely to occur on a warm, cloudy night when there is little wind?

29. T F When the dew point drops below the freezing temperature frost occurs?

31. ___________________________________________________________________________

32.___________________________________________________________________________

33. What are clouds and fog? ______________________________________________________________________________

34.What solid surface that consists of ice, salt, and dust allows for condensation to take place on?

__________________________________________

35. How large is a condensation nuclei? _________________________

36. Clouds can develop from two types of cooling.

_________________________________ and _________________________________

37.In Convective cooling as the air rises the temperature (drops) (rises).

38.Convective cooling is important in cloud formation because when the air cools to the dew point _____________________________ can occur.

Advective cooling is cooling produced when (39)__________________________ carries (40)___________________, (41)_______________________ air across a (42)_____________________ ocean or region of land.

Changes in temperature that result solely from the expansion and compression of air is called (43)________________________ temperature changes. The adiabatic temperature of dry air decreases about 1 degree Celsius for every 100 m the air rises.

44. The condensation level is the level at which clouds start to form. The condensation level is reached when the air reaches a level where its temperature is (lower) (higher) than its dew point.

45. Notice figure 24-5 in your book. At what temperature are clouds developing? _______________

What are the four types of precipitation?

75. ______________________________ 77. ______________________________________

76. ______________________________ 78. ______________________________________

Extremely cold temperatures near the ground sometimes produce clear ice pellets called (79)_______________________, which forms when rain falls through a layer of (80)_______________________ air. Occasionally rain does not freeze until it strikes a surface near the ground. In this event, it forms a thick layer of (81)_______________________ ice, or (82)________________________ ice.

83. Unlike sleet this form of precipitation form lumps of ice? ____________________________

84. Hail often forms with this type of cloud! ______________________________

What are the two causes of precipitation?

87. _____________________________ 88. _________________________________

89. T F A cloud droplet is smaller than the period at the end of this sentence.

90. T F Coalescence causes precipitation to form due to the colliding of many small droplets until its mass is to great to be supported by air.

91. T F Water droplets Coalesce until it contains 1000 times as much water as it did originally

92. T F Precipitation resulting from supercooling is found near the tropics.

93. T F Precipitation resulting from supercooling is caused by the coalescence of supercooled droplets on freezing nuclei.
