2.1. Overview of Air Pollutant Transfer

Try these first

1. 1.

   Define advection.

   Hint

   Think about how wind moves things.

2. 2.

   What is the lapse rate?

   Hint

   Connect it to how the temperature changes as you ascend.

3. 3.

   What is advection?

   • A. Vertical movement of air
   • B. Horizontal transport of pollutants
   • C. A reaction process

   Hint

   Think about how air moves pollutants from one location to another.

4. 4.

   True or False: Atmospheric stability can lead to higher concentrations of air pollutants.

   • True
   • False

   Hint

   Consider how stable air influences vertical movements.

5. 5.

   Calculate the change in temperature for an air parcel that rises 1 km, given the dry adiabatic lapse rate. How does this impact pollutant concentrations?

   Hint

   Use the lapse rate to find the temperature drop.

6. 6.

   Design an experiment to assess how varying mixing heights influence the dispersion of a pollutant in an urban setting.

   Hint

   Consider factors such as nearby buildings and wind patterns that might affect your results.
