5. Modeling Pollutant Transport

Try these first

1. 1.

   What is advection?

   Hint

   Think about how air moves and carries things with it.

2. 2.

   Define mixing height.

   Hint

   Look at where temperatures stabilize in the atmosphere.

3. 3.

   What process describes the movement of pollutants due to wind?

   • Dispersion
   • Advection
   • Stability

   Hint

   Think about how air movement affects pollution.

4. 4.

   True or False: Potential temperature is the temperature of an air parcel corrected for pressure.

   • True
   • False

   Hint

   Remember the definition related to pressure differences.

5. 5.

   A pollutant is released in a stable atmosphere. What factors might influence its dispersion and how would you model this in a box model?

   Hint

   Consider how stability and wind interact to affect pollutant behavior.

6. 6.

   Compare the concentration predictions for an area under an inversion layer to those on a clear day. What would the differences indicate for air quality?

   Hint

   Focus on how temperature layers influence dispersion.
