2.3. Velocity Gradient

Try these first

1. 1.

   What is a velocity gradient?

   Hint

   Think about how wind behaves at different levels.

2. 2.

   Define stability classes.

   Hint

   Remember the classification from unstable to stable.

3. 3.

   What primarily causes the velocity gradient?

   • Temperature
   • Surface Friction
   • Humidity

   Hint

   Think about the resistance wind faces as it approaches the ground.

4. 4.

   True or False: Stability classes describe wind speed only.

   • True
   • False

   Hint

   Consider what stability classes affect beyond just wind speed.

5. 5.

   Explain how a change in urban landscape (e.g., new tall buildings) might affect local velocity gradients and dispersion modeling results.

   Hint

   Consider the physical barriers and their impact on air movement.

6. 6.

   Propose a method for collecting wind data in a new industrial area for future emissions planning.

   Hint

   Think about the locations and heights where wind behavior varies significantly.
