22. Potential Evapotranspiration over India

Try these first

1. 1.

   What does PET stand for?

   Hint

   Think about evaporating water.

2. 2.

   Name one factor that affects PET.

   Hint

   Consider what the sun does to water.

3. 3.

   What is the main purpose of estimating PET?

   • To determine irrigation needs
   • To measure soil moisture
   • To assess crop health

   Hint

   Consider what farmers need to know about their water supply.

4. 4.

   True or False: Potential Evapotranspiration represents the actual evaporation that occurs in nature.

   • True
   • False

   Hint

   Think about ideal versus real conditions.

5. 5.

   Using the Penman-Monteith method, consider a location with known values for temperature, wind speed, solar radiation, and humidity to calculate PET. Present your findings.

   Hint

   Each parameter plays its role; check the definitions before calculation.

6. 6.

   Discuss how monsoon fluctuations can challenge the accuracy of PET estimations in coastal areas.

   Hint

   Focus on the impact of seasonal changes.
