Given an average day length of 15 hours, a mean monthly temperature of 30°C, and an empirical coefficient of 0.8, calculate the PET using the Thornthwaite Method.
💡 Hint: Don't forget to adjust each variable into the equation.
Compare the results of the Thornthwaite and Blaney-Criddle methods when estimating PET under the same climatic conditions in a tropical versus a temperate region. Discuss the differences in approach and reliability.
💡 Hint: Think about how each method uses different variables in climates.
