6.3. Dimensional Analysis

Try these first

1. 1.

   What is a box model in atmospheric studies?

   Hint

   Think about how we visualize changes in concentration over space.

2. 2.

   Define mixing height.

   Hint

   Consider how pollutants disperse in the atmosphere.

3. 3.

   What does a box model help to predict?

   • Air pressure
   • Pollutant behavior
   • Temperature variation

   Hint

   Think about the primary applications of box models.

4. 4.

   True or False: The adiabatic lapse rate changes with altitude.

   • True
   • False

   Hint

   Recall the definition of the adiabatic lapse rate.

5. 5.

   If the adiabatic lapse rate is -0.0098°C/m, how much will the temperature drop when an air parcel rises 500 meters?

   Hint

   Multiply the lapse rate by the height change.

6. 6.

   Describe how using a box model can help in urban planning regarding air quality control.

   Hint

   Think about pollutant sources and their expected dispersion.
