2.4.1. Looping Plume Shape

Try these first

1. 1.

   Define atmospheric stability in your own words.

   Hint

   Think of how well the air can 'hold onto' pollutants.

2. 2.

   What do we call the shape that pollutants take as they disperse?

   Hint

   It's a term we discussed that refers to the shape in which pollutants travel.

3. 3.

   What causes looping plume shapes?

   • High rainfall
   • High atmospheric turbulence
   • Stable conditions

   Hint

   Consider the definition of turbulent atmosphere.

4. 4.

   True or False: Coning occurs under unstable atmospheric conditions.

   • True
   • False

   Hint

   Recall the characteristics of different plume types.

5. 5.

   Given an unstable atmospheric condition, predict and illustrate the shape of a plume at various points in relation to the source. Discuss the implications for local air quality.

   Hint

   Consider the influence of wind and thermal gradients.

6. 6.

   Investigate the historical data of pollutant dispersion in your city and describe how different atmospheric conditions have affected the quality of air over time.

   Hint

   Utilize local environmental reports and meteorological data.
