2. Introduction to Box Models

Try these first

1. 1.

   Define mixing height.

   Hint

   Think about where pollutants mix effectively.

2. 2.

   What is the primary characteristic of an adiabatic process?

   Hint

   Consider the insulation of air while it rises.

3. 3.

   What defines the mixing height in the atmosphere?

   • Where pollutants become less concentrated
   • Intersection of environmental and adiabatic lapse rate
   • Height of the tallest building

   Hint

   Think about where pollutants effectively mix.

4. 4.

   True or False: Stability leads to better dispersion of pollutants.

   • True
   • False

   Hint

   Reflect on how air moves or doesn't move in stable conditions.

5. 5.

   A city has a high pollution level due to thermal inversion. Describe how mixing height influences this phenomenon and suggest a mitigation strategy.

   Hint

   Consider how the surroundings interact with air movement.

6. 6.

   Using the adiabatic lapse rate, calculate the temperature change when an air parcel rises 1000 meters.

   Hint

   Use the formula: Change in temperature = lapse rate * height change.
