3.1. Vertical Convection and Temperature Gradient

Try these first

1. 1.

   What is the dry adiabatic lapse rate?

   Hint

   Consider how temperature changes with height.

2. 2.

   What happens to warmer air compared to cooler air?

   Hint

   Think about the concept of buoyancy.

3. 3.

   What is the dry adiabatic lapse rate?

   • 9.8°C/km
   • 5.5°C/km
   • 10°C/km

   Hint

   Remember the standard value used in meteorology.

4. 4.

   True or False: In stable atmospheric conditions, pollutants are likely to disperse rapidly.

   • True
   • False

   Hint

   Think about air movement in stable conditions.

5. 5.

   Research a local air quality event where temperature inversions led to pollution outbreaks. Analyze the conditions and consequences involved.

   Hint

   Consider researching meteorological data during the event.

6. 6.

   Given varying temperatures at different heights, determine the presence of stable or unstable conditions and forecast environmental impacts.

   Hint

   Use illustrations of environmental lapse rates to guide your analysis.
