1.1. Lecture-39

Try these first

1. 1.

   What is mixing height?

   Hint

   Think about how pollutants spread in the air.

2. 2.

   Define atmospheric stability in simple terms.

   Hint

   Consider temperature changes during air parcel movement.

3. 3.

   What does the mixing height refer to?

   • The height of a building
   • The altitude where pollutants mix
   • The temperature of the air

   Hint

   Consider where mixing happens in the atmosphere.

4. 4.

   True or False: The adiabatic lapse rate changes depending on the emission source.

   • True
   • False

   Hint

   Think of the consistent value of the lapse rate.

5. 5.

   Given that the adiabatic lapse rate is -0.0098 °C/m, calculate the temperature of an air parcel starting at 25 °C at an altitude of 1 km.

   Hint

   Remember to account for the temperature change over the altitude difference.

6. 6.

   Design an experiment to measure the mixing height in a given urban setting. What variables would you consider?

   Hint

   Think about what affects air movement and pollution dispersion.
