Three cities have the following temperature (T) and dew point (T_d) during a July afternoon:

Atlanta, Georgia, T = 90°F; T_d = 75°F

Baltimore, Maryland, T = 80°F; T_d = 70°F

Norman, Oklahoma, T = 70°F; T_d = 65°F

(a) Which city appears to have the highest relative humidity?

(b) Which city appears to have the lowest relative humidity?

(c) Which city has the most water vapor in the air?

(d) Which city has the least water vapor in the air?

(e) For each city use Table 1 on p. 106 and the information on the same page to calculate the relative humidity for each city.

(f) Using both the relative humidity calculated in (e) and the air temperature, determine the heat index for each city using Fig. 4.21 (p. 108).
