20.3.2.c. Aerodynamic Method

Try these first

1. 1.

   What is the formula for the Aerodynamic Method?

   Hint

   Look for the components that influence evaporation.

2. 2.

   What does 'C' represent in the aerodynamic equation?

   Hint

   Think about what constant helps us compare different situations.

3. 3.

   What does the Aerodynamic Method primarily estimate?

   • Soil moisture
   • Evapotranspiration
   • Runoff

   Hint

   Think about what water loss process it measures.

4. 4.

   True or False: Wind speed has no impact on evaporation.

   • True
   • False

   Hint

   Remember how the atmosphere interacts with water surfaces.

5. 5.

   A researcher wants to compare ET in two adjacent fields. Field A has an average wind speed of 2 m/s while Field B has 4 m/s. If e_s and e_a remain constant at 2 kPa and 1 kPa respectively, how will the ET differ between the two fields?

   Hint

   Focus on how increasing wind speed affects the ET calculation.

6. 6.

   In a controlled experiment, a scientist finds that reducing e_a increases ET significantly. Provide a plausible explanation for this observation in relation to the Aerodynamic Method.

   Hint

   Consider how vapor pressure influences evaporation and why a deficit is crucial.
