Question:hard

According to Doorenbos and Pruitt, the Blaney-Criddle formula is not suitable for use in: (A) Equatorial regions where temperatures remain fairly constant, but other weather parameters change, (B) Large islands where air temperature is affected by the surrounding sea temperature showing little response to seasonal change in radiation, (C) High altitude where daytime radiation is practically independent of night temperature, (D) Climates with a high variability in sunshine hours during transition months, (E) Blaney-Criddle method should normally be applied for periods not greater than one month period. Choose the correct answer from the options given below:

Show Hint

Temperature-based formulas like Blaney-Criddle assume temperature is a reliable proxy for solar radiation.
In equatorial, maritime, or high-altitude regions where this correlation is weak, more comprehensive methods like Penman-Monteith must be used.
