2.4.3. Fanning Plume Shape

Try these first

1. 1.

   Define Fanning plume shape.

   Hint

   Think about how temperature differences affect air movement.

2. 2.

   What happens to pollutants at the mixing height?

   Hint

   Recall how mixing height interacts with plume shapes.

3. 3.

   What characteristic defines a Fanning plume shape?

   • Limited vertical dispersion
   • Increased vertical dispersion
   • No dispersion

   Hint

   Consider the temperature and mixing height interactions.

4. 4.

   In Fanning conditions, where do pollutants tend to remain?

   • True
   • False

   Hint

   Think of what happens below the source point.

5. 5.

   Evaluate how Fanning plume conditions might affect the design of air quality regulations in a city.

   Hint

   Think about possible pollution hotspots and their timing.

6. 6.

   Formulate a research question regarding the long-term health impacts of pollutants trapped during Fanning conditions.

   Hint

   Consider existing health studies that correlate pollution exposure.
