5.3. Generalized Transport Model

Try these first

1. 1.

   Define the term 'advection'.

   Hint

   Think about how wind moves pollution from one place to another.

2. 2.

   What is mixing height?

   Hint

   Consider how mixing might differ at different elevations.

3. 3.

   What is the primary process through which pollutants are carried by wind?

   • Dispersion
   • Advection
   • Reaction

   Hint

   Consider the role of wind in spreading substances in the atmosphere.

4. 4.

   True or False: The mixing height can vary throughout the day.

   • True
   • False

   Hint

   Think about how daytime heating affects air stability.

5. 5.

   Model the expected concentration levels at ground level for a pollution source that varies in height and stability from day to night.

   Hint

   Focus on the differences in stability based on the time of day.

6. 6.

   Evaluate how a rise in temperature can affect your pollution model in both stable and unstable atmospheric conditions.

   Hint

   Consider how temperature gradients determine mixing height.
