Challenge Problems
Push your limits with challenges.
Question 1
You have temperature readings at two heights containing variations. Calculate the Lm if the heat flux is 500 W/m² and friction velocity is 0.5 m/s. Discuss the importance of your findings.
💡 Hint: Consider the relationship of thermal flux to turbulence.
Question 2
Discuss how Lm's value might change between urban and rural settings, providing a theoretical explanation regarding surface characteristics and atmospheric interactions.
💡 Hint: Think about the environmental variables influencing measurement.
