- In terms of evaporation and condensation, what does it mean to say that air is saturated?
- Using Figure 4.5, estimate the saturation vapor pressure for air over a body of water with a temperature of 20 C.
- If the dew point temperature of the air is 10 C, what is the actual vapor pressure (use Figure 4.5)?
- Compute the relative humidity for the conditions given in question 2 and 3. If the air temperature cooled from 20 C down to 12 C, would the relative humidity increase, decrease, or stay the same?
- At what time of day is the relative humidity highest? Why?

- What is the name of a cloud exhibiting vertical development and producing rainfall?
- What is the composition of high clouds? Of middle clouds? Of low clouds?
- What does the term adiabatic mean?
- The dry adiabatic rate is about 10o C per kilometer; the moist adiabatic rate is about 6o C per kilometer. Explain why these two rates are different.
