1. Environmental Quality: Monitoring and Analysis

Try these first

1. 1.

   Define atmospheric stability.

   Hint

   Think about how rising air behaves.

2. 2.

   What is the dry adiabatic lapse rate?

   Hint

   Consider how temperature changes as you go higher.

3. 3.

   What is the significance of the dry adiabatic lapse rate?

   • It changes with altitude.
   • It remains constant regardless of conditions.
   • It establishes mixing height.

   Hint

   Think about the characteristics of dry adiabatic processes.

4. 4.

   True or False: Mixing height is only affected by humidity.

   • True
   • False

   Hint

   Consider what other factors might influence mixing height.

5. 5.

   Given an industrial source emits pollutants at a height of 50m. If the mixing height is 80m, what can be inferred about the dispersion of pollutants at ground level?

   Hint

   Consider how the relative heights affect pollution spread.

6. 6.

   A model predicts that with an increase in mixing height due to warming temperatures, pollutant concentrations will decrease. Discuss the mechanisms involved.

   Hint

   Think about how pollutants behave in warmer conditions.
