2.4.6. Trapping Plume Shape

Try these first

1. 1.

   Define plume.

   Hint

   Think about where smoke comes from.

2. 2.

   What happens to plumes in unstable conditions?

   Hint

   Consider the role of turbulence.

3. 3.

   What is the primary characteristic of a looping plume?

   • Stable dispersion
   • Rapid vertical movement
   • No dispersion

   Hint

   Think about how turbulence influences its behavior.

4. 4.

   True or False: Fanning plumes have significant vertical movement.

   • True
   • False

   Hint

   Consider the type of dispersal you remember.

5. 5.

   Calculate the mixing height if the environmental lapse rate is 5°C/km and the adiabatic lapse rate is 9.8°C/km.

   Hint

   Think about where the two lapse rates equalize.

6. 6.

   Given a scenario where pollutants are emitted from a source located below the mean mixing height, discuss the expected plume behavior and potential environmental implications.

   Hint

   Consider the effects of inversion and atmospheric stability.
