Question

For the hottest month of the year at the proposed airport site, the monthly mean of the average daily temperature is $39{}^{o}C$. The monthly mean of the maximum daily temperature is $48{}^{o}C$ for the same month of the year. From the given information, the calculated Airport Reference Temperature $\left(in{}^{o}C\right)$, is

• A. 48
• B. 36
• C. 39
• D. 42

Answer 1

The correct option is D 42

Airport reference temperature

$=T_a+\frac{T_m-T_a}{3}$
$T_a=$ Average daily temperature
$T_m=$ Maximum daily temperature
Given, $T_a={39}^o$
$T_m={48}^o$

Airport reference temperature
$=39+\frac{48-39}{3}=42{}^{o}C$
