Content

1. What factors affect the rate of evaporation?
2. How does temperature affect the water vapor content of the air?
3. What happens to the saturation vapor pressure when air temperature increases?
4. Does a change in air temperature cause the saturation mixing ratio to change? Why or why not?
5. Does a change in air temperature the actual vapor pressure (the vapor content) to change?
6. How is relative humidity calculated?
7. What two factors cause relative humidity to change from one day to the next?
8. What happens to relative humidity when the the air temperature decreases?
9. Why is the dew point temperature important?
10. How is the dew point temperature determined?
11. Does the dew point temperature change if the air temperature changes?
12. Does the dew point temperature change if the water vapor content of the air changes?
13. What are the two primary mechanisms for cooling the air?
14. How does the collision-coalescence process work?
15. How does the Bergeron ice crystal process work?
16. What are the global patterns to mean annual precipitation? Where is precipitation perennially high and where is it perennially low?
