2.4. Plume Shapes and Behavior

Try these first

1. 1.

   Explain what a plume is.

   Hint

   Think about the emissions from a chimney.

2. 2.

   What happens to pollutants in unstable atmospheric conditions?

   Hint

   Recall the definition of unstable conditions.

3. 3.

   What defines an unstable atmospheric condition?

   • High temperature
   • Low mixing height
   • Strong vertical mixing

   Hint

   What allows pollutants to rise into the atmosphere quickly?

4. 4.

   True or False: Coning plumes occur mainly under unstable atmospheric conditions.

   • True
   • False

   Hint

   Think about the difference between stable and unstable situations.

5. 5.

   Predict the pollutant dispersion for a factory release during a sunny day versus a rainy day considering stability effects.

   Hint

   Consider how weather impacts air stability.

6. 6.

   Explain the implications of incorrect temperature measurements while forecasting pollution in urban areas.

   Hint

   Think about the role of accurate data in public health safety.
